Abstract
In order to simulate the indoor environment in the commercial kitchen with the ceiling exhaust system, the plume above the cooking stove was modeled based on the measurement of temperature, velocity, concentration of CO_2 and SF_6 (as a tracer of contaminant die to cooking). Turbulent kinetic energy and length scale of turbulence. Gas cooking stove and IH cooking stove were tested. Gauss distribution was adapted to horizontal distribution of temperature, velocity and gas concentration, and the turbulent kinetic energy was modeled to be in proportion to the square of mean velocity. The length scale of turbulence was determined by CFD simulation when different values of length scale were assumed as parameter.
