MAE Colloquium - Qingyan ‘Yan’ Chen, Ph.D., (Purdue University), 'Inverse Design of Indoor Environment by CFD-based Optimal Methods'

Description

Qingyan ‘Yan’ Chen, Ph.D. James G. Dwyer Professor of Mechanical Engineering Purdue University Tuesday, Oct. 16, 2018, 4:00 pm | 203 Thurston Hall Refreshments at 3:30, 116 Upson Hall ABSTRACT The inverse design approach is new to indoor environment research and design community, though it has been used in other industries including automobile and airplane design. Inverse design concept uses the desired indoor environment as the design objective and inversely determines the systems required to achieve the objective. This seminar discusses a number of backward and forward optimal methods for inverse design. Backward methods can be used to identify contaminant sources in an enclosed environment. However, these methods cannot be used to inversely design a desired indoor environment. Forward methods, such as the computational-fluid-dynamics (CFD)-based genetic algorithm method, the CFD-based adjoint method, and the CFD-based proper-orthogonal-decomposition method, show the promise in the inverse design of airflow and heat transfer in an enclosed environment. This seminar will show some exciting examples of inverse design of indoor environment, discuss the pros and cons of each design method, and indicate the best approach in using the methods for inversely designing indoor environment.
