摘要：

External heat transfer coefficients from short quartz-coated cylindrical hot-film anemometer probes in mercury were evaluated by subtracting the thermal impedance of the quartz coatings from the overall thermal impedance of the sensors. The results are compared with those by Sajben for long enamelcoated wires and with available theory for infinite cylinders, and correlation equations are given. The low sensitivity of finite cylinders may be qualitatively explained by the persistence of end losses, i.e. by two-tauches conduction in the velocity-potential surfaces at arbitrary velocities. For comparison, results are also given for heat transfer to water. © 1969.
