Projects

This project presents an attempt to optimize a shell and tube heat exchanger. Of the various types of heat exchangers used in various industries the shell and tube heat exchanger is probably the most versatile, widely used in most industrial sectors and of the various designs of shell and tube, in this case we chose to design a U-tube shell and tube heat exchanger with one shell and two tube pass. While designing the heat exchanger in our project we provided the feed water in the shell side to cool down the engine oil that was supplied in the tube side. SOLIDWORKS was used as the software for designing the physical model and for the thermal calculations necessary for design optimization we used HTRI. We used TEMA type AEU as the standard in our project design. The effect of mass flow rate and fouling variations on other thermal parameters such as overall heat transfer coefficient, fouled heat transfer coefficient, film heat transfer coefficient, and heat exchanged and over design was analyzed in our project.

The CNC XY Plotter is required to plot two dimensional continuous or discontinuous data on a rectangular coordinate system. This project is done to fabricate a XY plotter using independent motion along X-direction and Y-direction, and microcontroller system (Arduino) to control those motions. Implementation of this project is carried out through the computer linked with the Arduino software, to which the G-code is transmitted by the Processing software. The plotter has been fabricated with cheap and available materials, retaining the accuracy and efficiency.
