Measurement Of Convective Heat Transfer For Various Checker Systems

The heat transfer properties of six different checkerworks were studied using a special test equipment. The temperature was deliberately limited to 300 deg C in order to measure the local temperature distribution of the air for the first time. The flow in the regenerator channels shows a considerable non-symmetrical appearance and local strands. Its enthalpy cannot be determined by the measurement of only one temperature. The heat transfer depends not only on the velocity of the flow (forced convection) but also on the temperature differences and resulting density differences of the fluid.
