Abstract
The pressure drops used in heat exchange of shell and tube type, the situations are particular and put ahead of the design exercise. In such situations, it is very desirable to make full use of the acceptable pressure drops in order to minimize the size of the heat exchanger. Heat exchanger design is Complex due to large number of design variables like shell diameter, tube pitch, baffle cut, tube diameter, baffle spacing, tube layout etc. in shell and tube type of heat exchanger. This design method is a taking time and intervening procedure. This is mandatory to design thermal and hydro mechanical procedure for this project performance. While fulfilling heat transfer requirements, it has anticipated to estimate the minimum heat transfer area and resultant minimum cost for a heat exchanger for given pressure drops. Effectiveness-NTU approach is the way developed for the design of shell-and-tube heat exchanger. The total number of transmit units, NTU, is scattered between shell and tube side. The methodology accounts for full use of given pressure drops on both sides of exchanger to yield the smallest exchanger for a given duty.
