Study on Heat Transfer of Heat Exchangers in the Stirling Engine : Heat Transfer in a Heated Tube under the Periodically Reversing Flow Condition

Abstract

Heat-transfer characteristics in heated tubes under periodically reversing low conditions have been investigated experimentally using a test apparatus that simulates the heat exchangers for the actual Stirling engine. The experimental correlation considering the influence of the piston phase-angle difference for the heat-transfer coefficient has been induced by the use of the working gas velocity evaluated from the Schmidt cycle model which is one of the ideal Stirling cycles
