Numerical investigation on heat transfer performance of Tesla valve-type pulsating heat pipe
摘要
Abstract
Based on VOF model,the D-type Tesla valve was arranged in the evaporator,condenser and adiabatic section of pulsating heat pipe,and the influence of Tesla valve on heat transfer performance of one-turn pulsating heat pipe was investigated numerically.The effect of setting position of Tesla valve on the start-up time,temperature,and thermal resistance was studied.The results show that the Diodicity of the Tesla valve can promote the flowing circulation,and the start-up and heat transfer performance of Tesla valve in the evaporator and adiabatic sections is better than that of conventional pulsating heat pipe.When the heating input is 2 W,the pulsating heat pipe of Tesla valve located in the evaporator has the shortest start-up time,and the pulsating heat pipe of the Tesla valve located in the adiabatic section has the shortest start-up at the heating input greater than 2 W.The thermal resistance of pulsating heat pipe integrated with Tesla valves in adiabatic and evaporator section is lower than conventional pulsating heat pipes by 10%-18%.The research can be the theoretical reference for the two-phase flow and heat transfer performance of the novel pipe-structure pulsating heat pipe.关键词
