Coupling calculation of temperature field for dry-type smoothing reactor

Abstract

As dry-type smoothing reactor is a crucial equipment of high voltage direct current transmission project, temperature monitoring is an effective means of inspecting its stable operation. According to computational fluid dynamics and heat transfer theory, steady state calculation of coupling fluid and thermal field for dry-type smoothing is done in the work. By simplifying the computational model of dry-type smoothing reactor reasonably, finite volume method is employed to solve the fluid and temperature fields of 1/4 circumferential region directly, and the distribution characteristics of the reactor temperature field is obtained. Then the axial and radial temperature distributions of encapsulation are researched separately. Finally, the accuracy of the simulation is verified by comparing the computational values with experimental values, the primary area of monitoring encapsulation temperature is proposed.
