Heat exchanger is one of the most important equipments with respect to heat transfer and energy saving in any system. Both cross flow and counter flow heat exchangers are used widely in the oil and petrochemical industries, cooling, storage of food and so on. They are used because they offer a large span of outputs, and they are easy to establish but have massive maintenance costs. Shell and tube heat exchangers are the most common the more one does a lot of chemical work such as producing oil. Tubular heat exchangers are divided into two types; the first kind are of circular cross-section whilst the others can be of other cross-sections such as ellipse, rectangle and some round flat twisted tubes. The core form can be changed quite easily by simply changing the diameter of the tubes and their length and configuration. As to the design, there are many opportunities for creativity to appear. Tubular exchangers can also deal with high external pressures, and also significant differences in the static head of the fluids. Tubular heat exchange devices are employed widely for transferring heat from one fluid to the other or from one of fluids and one phase change process, that is condensing or evaporation. With regard to the simulation strategy with the aid of CFD application, the approach will consist in the visualization and cross-sectioning of the main geometry of shell and cylinder heat exchangers. ANSYS 14. It is a simulation program and its parameter amounts to 0. A shell and tube heat exchanger with a spiral baffle will also be designed using the ANSYS programming tools in its most basic form; a shell. This will help to maintained the flow and the temperatures of the water and air inside the shell. Concerning heat exchanger type, there are three namely; Shell and tube type of heat exchangers has cylinder width of 20 mm, 1000 mm in length and shell width of 220 cm. These are consisting of 20 mm broad cylindrical shapes in each of the groups.
Because the temperatures of the shell and cylinder heat exchangers differ, the yield parameter is the temperature differential between them. To obtain more information, the prefix parameter (tube distance across) is used. Based on tubular heat exchangers, three types of models are created, and CFD analysis is performed in ANSYS 14.0. So, the best section of a heat exchanger for regulating water temperature may be identified, and this is how it works.
