doi:10.12068/j.issn.1005-3026.2018.09.009

Abstract

Abstract: The impingement heat transfer performance of jets from conical and cylindrical nozzles was studied. Under the same initial and boundary conditions， the simulations of coupled heat transfer and fluid flow in the impingement heat transfer process of the two nozzles were conducted by using computational fluid dynamics software Fluent. The fluid flow and temperature field data at the fluid-solid interface， such as static pressure， shear stress， turbulence intensity， convection heat transfer coefficient， were compared and analyzed. The simulation results show that the heat transfer performance of jet from conical nozzle is better than that from cylindrical nozzle. The conclusions obtained are of guiding significance to the design of nozzles for ultra fast cooling equipment of hot rolled steel.

Key words: jet nozzle, jet cooling, heat transfer, ultra fast cooling, Fluent
