- In this report the results of experimental investigation on the influence of pollution on heat characteristics of tube with longitudinal fins are presented. The thickness of polluting on the finned surface in different time moments is measured. The dynamic of growth for polluted thickness is determined. As follows from experiments, the profile of polluting along the height of fins is near to trapezoidal. The temperature distributions in fins and total heat fl ux conducted by finned wall at the different time moments are found. The presence of pollution on the finned surface leads to change of temperature distribution in fins which substantially differ from the similar distributions for "clean" fins. The questions connected with the choice of the optimum dimensions of fins being polluted are discussed. It is shown that the optimum dimensions of fins are dependent on the value Biot number of polluting.
