| Abstract: | Fouling effect on heat transfer around a cylinder in cross-flow was investigated numerically by ANSYS software
programme using finite element method. Calculations were made with variable local heat transfer coefficients, constant freestream
temperature and constant clean tube surface temperature. Heat transfer rates were presented for different cases with
temperature field. Deposit thickness formed around the cylinder was fixed as follows: i) Non-uniform thickness of fouling
shape was calculated with homogenous condition; ii) Non-uniform and non-homogenous fouling shape was considered; and
iii) Effect of eccentricity was calculated for non-uniform and non-homogeneous cases. Numerical predictions were made as
temperature contours through thickness of fouling and Qfoul / Qclean was plotted against the position of fouling. |
