Heat transfer in a horizontal coiled pipe in a transient regime and at a near-critical pressure of a fluid

Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

It has been established that in the region of pressures close to a critical one, heat transfer in a transient regime of motion of a single-phase flow in a horizontal coil pipe changes nonuniformly over the cross section of the perimeter. The main factors here are the influence of inertia forces and of free convection. Equations to calculate the heat-transfer coefficient are suggested.
