Abstract
Describes the development of the Cold Tip Velocity Meter using a thermo-cooling unit for a conical surface, the temperature of which depends on the volume of water over the surface. The measurement of low velocity is important. The theoretical mean velocity characteristics of the cold conical tip were investigated by solving simultaneously the LaPlace Equation for the heat flow within the cone and the boundary layer equations for heat flow through the boundary layer over the cone. The dynamic behaviour of the instrument was further studied in unsteady flow states, and by comparison with a quartz coated hot film anemometer. Finally the Cold Tip meter was used to measure turbulent velocity fluctuations in a wake showing pronounced periodicity.
