Abstract This article aims to reveal the transient thermal characteristics of the solid domain in a nozzle flowmeter when
measuring fluids of varying temperatures. Based on finite element method, the transient numerical calculation of
the thermal characteristics of each component of the nozzle flowmeter has been conducted. The 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… More >
