Notes:
A study was made of the deviation between the temperature of thermocouple junctions and the temperature of the fluid surrounding them which arises as a result of conduction along the thermocouple leads. Measurements around a 1/2-in. heated sphere in the plane of the equator normal to an air stream having a velocity of 16 ft./sec. were made with a 0.001-in.-diam. thermocouple of platinum and platinum rhodium. Air temperatures in the boundary flows of the sphere were predicted from the indications of the thermocouple. The method of prediction employed also determined the heat transfer coefficients for the thermocouple wire in the boundary layer. These local heat transfer coefficients are lower than those observed in a uniform stream having a velocity equal to the estimated local velocity in the boundary layer.
