Professor Wei Wang's research lab specializes in computational fluid dynamics and combustion science, with a focus on developing high-order numerical methods for stiff reactive flows and turbulent combustion. The lab investigates advanced numerical schemes, such as modified fractional step methods and high-resolution finite-difference techniques, to accurately capture discontinuities and reaction fronts in complex flow systems. Experimental validation is conducted through high-fidelity wind-tunnel studies, including particle image velocimetry (PIV) and hot-wire anemometry, to study natural ventilation and indoor airflow in building models. The integration of advanced numerical simulations with experimental data enables the lab to address challenges in energy-efficient building design and clean combustion technologies.

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
