A Three-Dimensional Simulation of Temperature and Water Vapor Distributions between a Heat Source and a Ventilating Hood

摘要

Numerical simulation of air motion inside a kitchen is carried out in the presence of heat generation associated with the cooking process. A preliminary analysis on the heat removal capability is conducted under different capture velocities of the ventilating hood. A critical hood capture velocity is determined to provide a minimum requirement for efficient removal of heat and thus provide thermal comfort in the kitchen. A detailed investigation of the make-up air arrangements, radiation effects, effluent transport is under progress and will be discussed during the presentation.
