Simulation of Water Mist Spray for Commercial Kitchen Ventilation (CKV) System Using Ansys-CFD

Abstract:

Concept of the water mist spray in CKV system is to clean the gas filter at kitchen hood. This research aims to analyze the behavior and flow characteristics of water mist spray produced by spray nozzle. A computational fluid dynamics (CFD) model with k-epsilon turbulence method is a simulation tool for the characterization of sprays. The fluid flow for case1, case 2 and case 3 have the same pattern type of graph. Changes have seen in fluid flow pressure and velocity. The value of fluid flow pressure was decreasing from the first point at water inlet until to the last point at nozzle orifice. The total pressure values for case 1, case 2, and case 3 are 99.997 kPa, 199.991 kPa and 299.992 kPa respectively. The highest velocity is recorded at the liquid tip of the nozzle which is about 144.15 m/s for case 3. In the other hand, the highest value of fluid flow pressure was recorded at the water inlet part.
