Steady-State Longitudinal and Radial Temperature Distributions in Internally Heated Finite Wires

The differential equation for the steady-state simultaneous longitudinal and radial temperature distributions in electrically heated finite cylinders with ends at the ambient temperature has been set up and solved for variable Q and constant h and k. The effect of variable Q and the constant k. Radial temperature gradients were and constant k. Radial temperature gradients were computed under several assumptions. Example calculations are presented for comparsion. A method of selecting a desirable test section length for predetermined iven. A method is given for estimating the mid-length temperature from a measured mean temperature and operating conditions. (auth)
