MASS TRANSFER POTENTIAL CAPACITY DISSIPATION EXTREMUM PRINCIPLE AND DECONTAMINATION VENTILATION OPTIMIZATION

CHEN Qun REN Jian-Xun (School of Aerospace,Tsinghua University,Heat Transfer and Energy Conversation-The Key Laboratory of Beijing Municipality;Beijing 100084,China)  
In the interest of designing an efficient ventilation arrangement to decrease contaminant concentrations,the heat transfer potential capacity dissipation extremum principle is extended to convective mass transfer analysis.The mass transfer potential capacity dissipation function is defined, and then the convective mass transfer field synergy equation is obtained by seeking the extremum of the mass transfer potential capacity dissipation function for some constraints.This equation can be solved to obtain an optimal velocity distribution to decrease the mass transfer potential dissipation and the contaminant concentration.These results provide guidance for optimizing ventilation system designs.
