Abstract:

Izumi has investigated the commencement of the natural convection flow inside of a vertical circular tube. The quasi-incompressible fluid is initially at rest with a uniform temperature the same as the wall temperature. At time t 0, the wall temperature is suddenly changed. With a body force acting in the axial direction, a natural convection flow starts owing to the transient non-uniform temperature field established in the fluid. Izumi only investigated the case where the wall temperature is uniform at all times. In practice, it is more likely to find a change of the wall temperature from the initial uniform value to a new non-uniform distribution. The ensuing flow will no longer be axisymmetric as in Izumis work. It is our object here to examine such transient non-axisymmetric flows. Author
