Abstract

The possibility is investigated to use a water tunnel with variable fluid-temperature to achieve high Reynolds numbers for hydrodynamic and aerodynamic testing. Characteristics of such a water tunnel are compared to those of a low-speed wind tunnel operating at normal conditions, on the basis of same Reynolds number in both tunnels. The advantages offered by the variable-temperature water tunnel as to tunnel dimensions, power requirements, and observation times, led to a preliminary design of a small pilot water tunnel with heating and cooling of the fluid, which is presented. The problem of cavitation is considered and found to be not very restrictive for testing practical configurations.
