The wind tunnel consists of a flow path, the device under test, sensors and active elements. The flow path consists of a straight section with flow elements to ensure equal flow into all sections of the heat exchanger which is the device under test. Sensors are placed so that inlet and outlet temperatures, pressure drops, and mass flow rates can be measured for both the internal-side fluid [coolant, charge-air, or oil] and the external-side fluid [ambient air]. The inlet temperature of the internal-side fluids, the mass flow rates of both the internal-side and external-side fluids are controlled. Analysis of the data enables pressure drop and heat transfer characteristics to be determined. The wind tunnel has enabled Richardson Cooling Packages to develop and analyze new tube and fin designs.
Richardson Cooling Packages is grateful for an Innovation Works Innovation Adoption Grant and for the expert guidance provided by the late Ralph L. Webb, a recipient of the ASME Heat Transfer Memorial Award.
