Analysis of overall Heat transfer in Shell and tube heat exchanger can be done by changing various structural parameters, such as baffle cut, space between baffles, shape of baffles or tube shape and size. In this report, all the analysis is done on the shell side. Analysis of shell side fluid temperature and heat transfer is done by using a commercial CFD package. Study is done on a single pass shell and tube heat exchanger with turbulent flow. Simulation data are obtained for shell and tube heat exchanger with helical tube and inclined baffles (25% and 36% cut) with inclination angle of 5 ,...

Diesel engines are playing a vital role in the field of transportation and power generation. In the present world, much research is going on in the field of renewable energy to replace conventional sources of energy. But it is not very easy to replace diesel engines with other engines when power and reliability are the factors that matter. The emissions from diesel engines are very harmful to the environment and to human health. The major emissions are NOx and smoke which need to be controlled in an effective manner. This experimental investigation was carried out to find out suitable...
