A thermally comfortable and healthy indoor space is very important for its occupants. To create such an indoor space with low energy consumption requires proper design and control of its air distribution. This talk first introduces the validation of turbulence models and fast fluid dynamics for indoor air distribution prediction. This talk then introduces a validated computational fluid dynamics (CFD)-based adjoint method to inversely identify an optimal air distribution system, such as the air supply location, size, and parameters, for creating the desired space. Further, we will discuss the enhancements of the CFD-based adjoint method by fast fluid dynamics and coarse grid techniques. This seminar will outline the future challenges and opportunities.
Wei Liu is a PhD candidate in the School of Mechanical Engineering at Purdue University. Wei received his B.Sc. degree from Tianjin University, China in 2009 and M.Sc. degree from Purdue University in 2014. He has conducted research on simulations and measurements of airflow and contaminant dispersion in enclosed spaces, such as building and airplanes. Inverse design of air distributions in enclosed environment is his Ph.D. thesis topic. Wei has published more than 20 journal papers. He was a recipient of ASHRAE Grant-in-Aid award, won the first prize for a computational-fluid-dynamics shootout contest from ASHRAE, and is a Bilsland Dissertation Fellow at Purdue University.
