M.I.T. Stirling-cycle heat transfer apparatusThe design and construction of a two-cylinder apparatus to measure heat transfer under conditions of oscillating pressure and oscillating flow such as found in Stirling-cycle machines are described. The apparatus consists of two large single-stage air compressors joined by a rigid drive shaft between the two crack shafts, and is powered by a 25-hp variable speed DC motor. The apparatus is capable of measuring heat transfer while velocity and pressure change over the range of dimensionless parameters normally found in Stirling cycle machines. It allows each parameter to be varied independently and easily. Instrumentation for the apparatus is adequate for measurement of pressure, time, gas and wall temperature, wall heat flux, and gas velocity. It yields preliminary data which show that the apparatus and data acquisition are operating satisfactorily and produce reasonable results.
