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.
