Report Number: R16E0046 Responsible Representative: Keiichi Kitamura(Yokohama National University) Contact Information: Takuya Aogaki(aogaki-takuya-rf@ynu.jp) Members: Keiichi Kitamura, Takuya Aogaki, Ryusuke Yamagata Subject Category: Space(Rocket,Space transportation) Abstract We conducted numerical analysis on a slender body configuration which mimics a reusable rocket. In this study, we acquired detailed flowfields which have not been obtained from previous experiments and related them with aerodynamic characteristics. As a future work, by reference to our results, we will install aerodynamic devices and examine configurations to get better・・・<<read more>>

Report Number: R16E0044 Responsible Representative: Shun Takahashi(Tokai University) Contact Information: Shun Takahashi(takahasi@tokai-u.jp) Members: Shun Takahashi Subject Category: Space(Rocket) Abstract Two-phase flows with moving objects are commonly used in practical engineering products. This study issubject to investigate the effect of the micro particles in the exhausted gas from the rocket engine to the strong pressure waves and the thermal conductance modification due to the water film around the menisci in the heat pipes. These multiphase flows that are important from the・・・<<read more>>
Report Number: R16E0042 Responsible Representative: Susumu Goto(Osaka University) Contact Information: Susumu Goto(goto@me.es.osaka-u.ac.jp) Members: Keita Hanajima, Tetsuya Kawabe, Susumu Goto, Ken Komoda, Jun Kanki Subject Category: Basic Research(Numerical analysis,CFD) Abstract Turbulence is ubiquitous. Interestingly, small-scale eddies in turbulence have universal properties, which are independent of the kind of turbulence. We aim at reviewing the physics of this universality and constructing new turbulence models which can be applied to many problems in aerospace engineering. Goal Fully developed turbulence is ubiquitous in the・・・<<read more>>
Report Number: R16E0041 Responsible Representative: Soshi Kawai(Department of Aerospace Engineering, Tohoku University.) Contact Information: Soshi Kawai(kawai@cfd.mech.tohoku.ac.jp) Members: Hiroyuki Asada, Soshi Kawai Subject Category: Aviation(Body sound) Abstract Low-noise devices for reducing airframe noise of aircrafts have been studied and developed in many literature, but the details of interaction between each device are insufficiently investigated. This study develops discontinuous Galerkin (DG) based high-fidelity numerical schemes for compressible turbulent flows around aircrafts to enhance guidelines for designing next-generation low-noise aircrafts by clarifying the・・・<<read more>>
