Wei Wang教授の研究室では、反応流体力学や燃焼流の高精度数値解析に注力しており、特に時間スケールが極めて短い反応を扱う stiff 問題に対して、高次の差分法と分離型時間積分法を組み合わせた新規数値解法を開発しています。実験的手法（PIVやHWA）を用いた風洞実験による自然換気の高分解能計測データの収集も併せて行い、数倉と実験の融合による都市・建物環境の流れの解明を目指しています。

A new high order finite-difference method utilizing the idea of Harten ENO subcell resolution method is proposed for chemical reactive flows and combustion.In reaction problems, when the reaction time scale is very small, e.g., orders of magnitude smaller than the fluid dynamics time scales, the governing equations will become very stiff.Wrong propagation speed of discontinuity may occur due to the underresolved numerical solution in both space and time.The present proposed method is a modified
This data article provides temporally and spatially high-resolution datasets of the indoor velocity fields for cross-ventilation models of two-layered simplified buildings separated by a second floor at the middle height with an opening using wind-tunnel experiments. The datasets are based on the research article entitled "Quantifying natural cross-ventilation flow of a two-layered model used for terraced houses in tropical zones by particle image velocimetry" by Ali et al. [1]. Two cases are co
