  • Mushroom-cloud development and transport of radioactive materials and dust: A numerical study of the Nagasaki atomic bombing

    Nakajima K., Matsuo A.

    Progress in Earth and Planetary Science 13 ( 1 )  2026.12

     View Summary

    In this study, the blast-wave formation and mushroom-cloud development associated with the Nagasaki atomic bombing were numerically investigated to construct initial conditions for subsequent meteorological simulations of “black rain.” To evaluate the three-dimensional transport of hazardous materials within the cloud, two distinct material tracers were treated as passive scalars in an Eulerian framework and solved together with the compressible airflow: bomb-derived radioactive material, assumed to represent plutonium released from the bomb, and ground-derived dust, representing non-radioactive smoke and dust associated with urban fires and disturbed surface materials. The computation was carried out in three stages: a one-dimensional theoretical blast-wave calculation, a high-resolution three-dimensional simulation of the early blast-wave/fireball interaction, and a large-domain three-dimensional simulation of the subsequent mushroom-cloud rise. The numerical results showed that sufficient grid resolution is required in both the blast-wave and mushroom-cloud stages to reproduce the cloud-rise behavior accurately. In the blast-wave stage, coarse grids smeared the reflected-shock/fireball interaction and led to an underestimation of the later cloud-top height. The background atmospheric profile also affected the buoyant rise, and a dry adiabatic atmosphere showed better agreement with historical nuclear-test data than the International Standard Atmosphere. The three-dimensional blast-wave simulation clarified that the reflected shock wave deforms the fireball and induces a strong axial updraft, which provides the initial flow structure for the subsequent mushroom-cloud rise. The mushroom-cloud simulation reproduced the buoyant ascent of the hot fireball, the horizontal spreading of the cloud head, and the development of a vortex-ring structure. The potential-temperature perturbation field visualized the hot core and updraft, while the relative-humidity field indicated possible condensate-cloud formation in the upper part of the cloud. The two solid-phase components exhibited distinct transport behaviors depending on their initial locations. Ground-derived dust was entrained mainly through the central updraft, whereas bomb-derived radioactive material was preferentially incorporated into the vortex-ring region around the cloud head. These results provide the three-dimensional initial distribution of hazardous materials for meteorological simulations of black rain. (Figure presented.)

  • Symmetric, Square, Lattice Pattern Injector Design and Experimental Flow Characterization within a Detonation Engine

    AIAA Science and Technology Forum and Exposition AIAA Scitech Forum 2026  2026

     View Summary

    Flow inside a rotating detonation engine (RDE), which is studied for use in aircraft and rocket propulsion, is affected by the geometry of the injector component. Typically, RDEs are cylindrical in nature and have a circular injection pattern. However, although hollow RDEs are now being studied, the injector pattern has remained the fixed-radius, circular injector pattern. In order to understand the impact of uniform injection across the entire cross-sectional area of a combustor inlet, the current research sought to conceptualize, design, and test a bi-propellant RDE with a symmetric injector pattern, and elucidate detonation propagation. In this investigation, different injector patterns concepts were studied, and a symmetric, square, lattice pattern injector was designed and fitted to a square combustion chamber. Combustion tests were conducted with mass flowrates between 30-38 g/s, equivalence ratios between 1.0-1.6, and from back pressures of approximately 5 kPa. Experimental data revealed unidirectional detonation wave motion, reflected waves coexisting with the detonation wave under stable operation, non-uniform pressure near the combustor inlet, increased wave velocity compared to a previous hollow engine tested at Nagoya University, potentially improved reactant mixing in the chamber, and a 94° phase shift when decomposing the detonation wave motion into rectangular coordinates.

  • Operating Characteristics of Rotating Detonation Engine with Different Liquid Fuel for Next Sounding Rocket Space Flight

    AIAA Science and Technology Forum and Exposition AIAA Scitech Forum 2026  2026

     View Summary

    Liquid propellants are widely used in rocket engines, and investigating the operational characteristics of RDEs using liquid propellants is essential for their practical application. In this study, combustion experiments were conducted on a single-annular RDE using liquid propane and liquid nitrous oxide as propellants, and its operational characteristics were evaluated. As a result, successful operation in the detonation mode was achieved with an operating frequency of 15–16 kHz. However, a gradual decrease in the propane mass flow rate was observed during combustion. This behavior was attributed to the possible occurrence of vapor lock in the propane injector feed lines caused by heat generated during combustion. To examine this possibility, the injector feed line wall temperature was calculated using the heat conduction equation under the assumptions of a one-dimensional semi-infinite solid, a constant incoming heat flux, and single-phase liquid flow in the injector. The results showed that for an incoming heat flux of q=0.2 MW/m2, the wall temperature near the injector outlet exceeds the boiling temperature of propane, indicating the potential for bubble formation at the injector outlet.

  • Numerical Evaluation of the Thermal Response of HIMICO with a Cork-Sandwich TPS

    Kashiwakura K., Matsuo A., Shima E., Taguchi H., Takahashi H., Momose M.

    27th AIAA International Space Planes and Hypersonic Systems and Technologies Conference  2026

     View Summary

    In this study, a three-dimensional conjugate heat transfer (CHT) analysis was conducted for the entire hypersonic experimental vehicle (HIMICO), including its internal thermal protection system (TPS), to evaluate the thermal response characteristics and thermal integrity of the vehicle under the wind tunnel test conditions at Ramjet Engine Test Facility in JAXA. The results indicated that, after 30 s of exposure to the high-temperature flow, the temperatures of certain regions of the Ti-6Al-4V structural components and the Cork insulation material exceeded their allowable operating limits, suggesting the potential for degradation of material strength and deterioration of thermal insulation performance. Comparison with wind tunnel test data showed good agreement in the surface temperature distributions at both the nose cone tip and the wing region, thereby demonstrating the validity of the present analysis approach. Furthermore, the results revealed that small geometric features, such as bolt holes, can significantly affect localized temperature rises and should therefore be considered in detailed thermal design evaluations.

  • Design Analyses and Demonstration Tests of High-Mach Integrated Control Experiment Aircraft (HIMICO)

    27th AIAA International Space Planes and Hypersonic Systems and Technologies Conference  2026

     View Summary

    Design analyses were conducted on the hypersonic integrated control experimental aircraft (HIMICO) that flies at Mach 5. Aerodynamic performance of the aircraft was obtained by hypersonic wind tunnel experiments and CFD analyses. Structural feasibility in a high-temperature flight environment was confirmed by fluid-structure coupling simulation and structural analyses. The control law of hypersonic air intake was confirmed by hypersonic wind tunnel test. The control law of hydrogen ram combustor was confirmed by direct connect combustion experiments. The aerodynamic force measurements and flow field measurements for propulsion wind tunnel tests with Mach 5 flight simulating condition were prepared. Mechanical environment tests of onboard equipment were conducted simulating the onboard environment of sounding rocket.
