ABSTRACT

A new probe for combined measurements of an instantaneous heat flow to a wall, longitudinal component of skin friction vector, and of wall pressure is presented. The design and principle of operation of the probe are described. Results of some tests are presented. The estimated measuring characteristics used have shown that the probe can be used for combined measurements of instantaneous longitudinal component of skin friction vector, pulsations of heat flow to the wall, and of the wall pressure in a turbulent flow.
