Abstract:
How about an imaginary extra wind tunnel for car radiators and heaters? Same capacity and accuracy as the one You already have. Presenting results within seconds instead of hours. Small investment costs. Drawback: You first have to run an extended test in a real wind tunnel.A test method, with a combination of 16 different flow rates is used. Regression analyses of results, will present a set of equations that can describe the total response to varying flow rates. Prediction of heat exchange and pressure drops for any combination of air and liquid flows can be made with an accuracy better than ± 2 %.
