主　　题：Nozzle flowmeters numerical calculation transient thermal characteristics 

摘      要：This article aims to reveal the transient thermal characteristics of the solid domain in a nozzle flowmeter when measuring fluids of varying *** on finite element method,the transient numerical calculation of the thermal characteristics of each component of the nozzle flowmeter has been *** research shows that:as the fluid passes through the flowmeter,the high heat flux area inside the nozzle flowmeter gradually transfer from the center of the nozzle to the inlet and outlet,as well as the pressure tapping points upstream and downstream;High thermal stress zones are present near the upstream and downstream pressure tapping points and inlet and outlet area;High thermal deformation zones occur near the upstream and downstream pressure tapping points and eight slot nozzle.
