The process in solving simulation consists of modelling and meshing the basic geometry of shell and tube heat exchanger using CFD package ANSYS 12.0. The objective of the project is design of shell and tube heat exchanger with helical baffle using catia software and study the flow and temperature field inside the shell using ANSYS software tools. The heat exchanger contains 27 tubes and 5490 mm length shell diameter 540 mm. The helix angle of helical baffle will be varied from 0 to 200 degree. In simulation, we will show how the temperature and heat flux vary throughout the surface of the condenser. The flow pattern in the shell side of the heat exchanger with continuous helical baffles was forced to be rotational and helical due to the geometry of the continuous helical baffles, which results in...

We carried out the machine to determine their suitable dimensions based on loading and stresses due to them. We used available local material and tool from a private workshop. We also made use of some machine tools in the college workshop. This objective of this thesis work is to analyze drilling operation and the taper turning in the turning operation. A number of tests are performed with different cutting speed and feed rates. The experiments are carried out and the results are plotted in the form of graphs. These graphs show the variation of cutting forces and cutting speed .UsingScatterwhich helped to find out torque and thrust force graphs with different control factors like feed, speed etc. the piezoelectric dynamometer has been used for measuring thrust forces and torque on varying the feed rate, speed, and d...
