| Outline of Annual Research Achievements |
The conjugate heat transfer (CHT) solver based on compressible flow framework which can calculate the convection in the fluid and the conduction in the solid simultaneously has been developed. However, due to the different scales of the characteristic velocities between the fluid and solid, the extremely smaller time step is inevitable. To overcome this problem, the Adaptive Time Scheme developed by authors for computational aeroacoustics is under modification to be applied to CHT problems to increase the time step to save computational time. Besides, to validate the current framework, the simulation of the natural convection and heat conduction around and in a horizontal circular pipe is studied.
