Description

By: Kishor Khankari, Ph.D. Dr. Kishor Khankari, Ph.D. is President at AnSight LLC in Ann Arbor, MI. He provides engineering solutions and insights through Physics based simulations and CFD analysis. Kishor has several years of experience in providing optimized HVAC solutions to a wide variety of applications involving external wind engineering, plume dispersion, smoke exhaust, displacement ventilation, natural ventilation, radiant heating and cooling, and indoor air quality and thermal comfort optimization for office spaces, patient rooms, operating rooms, cleanrooms, justice facilities, data centers, and warehouses. Dr. Khankari has developed a patented technology of a wind band design of exhaust fan assembly systems. He has developed several easy-to-use analytical software tools which are regularly used by design engineers in a variety companies including those in HVAC industry, critical facilities, and automotive industries. A noted expert in his field, he has a Ph.D. from the University of Minnesota and has been regularly published in several technical journals and trade magazines. Dr. Khankari has delivered close to 100 DL presentations worldwide on topics related to design and optimization of HVAC systems and made several presentation at various technical conferences and professional meetings. Dr. Kishor Khankari is a Fellow member of ASHRAE. He is currently serving on ASHRAE Board as a Director-at Large. He is a recipient of ASHRAE Exceptional and Distinguished Service Awards. He is the past President of Detroit ASHRAE Chapter, past Chair of ASHRAE Technical Committee TC9.11 Clean Spaces, and past Chair of Research Administration Committee (RAC). He is a voting member of Technical Committee TC9.10 Laboratory Systems and TC5.3 Air Distribution. He is also leading a new Multi Task Group (MTG) on Air Change Rates Application of Computational Fluid Dynamics (CFD) for Built Environment (AIA and GBCI approved) Air is the primary carrier of heat, moisture, and contaminants in and around built environments. Airflow patterns determine the distribution of temperature, contaminant level, and importantly air quality and thermal comfort of occupants. The HVAC design risk due to poor airflow management is often realized after commissioning and occupancy. Sometimes it is too late to mitigate the issues related to poor airflow management. This presentation will show how Computational Fluid Dynamics (CFD) can help in identifying such risks at early stages in the design and help optimize the HVAC designs for effective and energy efficient performance. After providing a brief introduction to CFD, this presentation with the help of several case studies will show applications of CFD for a wide variety of scenarios involving displacement ventilation, active and passive chilled beams, airflow patterns in enclosed spaces, radiant heating and cooling, smoke propagation in atria, clean rooms, data centers, patient rooms, laboratories, plume dispersion from cooling towers, and several other similar applications to built environment Networking - 11:30AM to 12:00PM Presentation - 12:00PM to 1:00PM
