Forced convection and heat transfer around a bounded cylinder.

Popis výsledku v původním jazyce

The article deals with the heat transfer solution in the fluid flow inside a pipe, the small tube is inserted into the pipe and its axis is perpendicular to the axis of the pipe. The fluid is water, the regime of the fluid flow is turbulent. The small tube is loaded by the internal source of the heat, the power of the source is constant and homogenous over the small tube surface and the cold water cools down the small tube. The analysis of the described problem helps to design the experimental model (the heat source above all) to validate the CFD results. The work included the numeric and analytic method. The model was prepared with the aim to investigate large amount of the variants of the geometric set up (the tube and pipe diameters ratio, i.g the geometrical aspect ratio, corresponding stabilization length of the pipe for given diameter), the flow properties (variation of the velocity values, i.g. Reynolds number) and the power of the heat source (ensuring the measurable differences of the temperatures on the tube surface, i.g. large Nusselt number). The effect of the constrained space has been observed and described, compare to the free fluid flow.
