Sažetak
In this paper numerical and experimental analysis of compact heat exchanger has been done. A fin and tube heat exchanger composed of four rows of circular tubes has been installed in an open circuit wind tunnel. Air and water were used as working fluids. Same geometry and parameter setup has been analyzed using commercial fluid flow and a heat transfer solver Fluent. Air/water side model has been used because it gives more accurate results than simpler model that includes only air side flow. Comparison between numerical model and experimental results has been accomplished with respect of air and water temperature. It has been shown that numerical model results coincide well with the experimental data, with deviations within an acceptable range. Therefore, used air/water side model can be used for further investigation of more efficient compact heat exchanger geometry.
