| Abstract | ||
| This investigation represents a computerized model for the thermal-hydraulic design of a single shell – single pass of enhance tube bundle heat exchanger using the step by step technique (SST). The design procedure suggested in this study is also suitable for multi-tube passes using the most familiar methods of design of shell and tube heat exchanger such as Kern and Bell-Delaware. The (SST) was considered as a basic in order to incorporate the effect of the physical property change due to temperature variation along the heat exchanger. The model basic design depends on the selection of the low finned tube characteristics. The use of such surface will have the advantage of avoiding the space restrictions of the equipment layout in the industrial applications and reduction in the cost of manufacture machining as well. The model was intended to be a choice for the lubricating oil cooling system of a gas turbine power station in Debis-Kirkuk plant. The verification of the model showed that using such enhanced tubes in the cooling system will improve the operating conditions especially during summer season in Iraq. | ||
