Varahagiri V S J Bhaskar; Dr. Mohammad Israr

This paper is the continuation of previous papers {[IJERMCE-IFERP-DOI-802] and ISSN (Online): 2456-1290} Volume 1, Issue 2, May 2016, and {[IJERMCE-IFERP-DOI-803] and ISSN (Online): 2456-1290} Vol 1, Issue 3, July 2016 as we found in paper 1- Mexican Hat is the best piston bowl for efficiency, in paper 2 – we found Mexican Hat 120cc is the best in performance. In this paper we have added 3mm Tangential Slottes, total 04 in numbers. We are unable to find the Result and Analysis of Slotted Piston bowl in IC Engine Solver V15.0 That’s why we have used Transient Thermal Analysis for finding the relation of different parameters of engine i.e. Turbulent Kinetic Energy, Turbulent Intensity and Turbulent Dissipation Rate for Mexican Hat 120cc piston which were compared with different configurations of Models like AVL, Hasselman, Mitsubishi, Pan and Shallow Hasselman. CFD analysis is carried out on a diesel engine using different configuration pistons which was found 120cc Mexican Hat four stroke engine have best performance. Corresponding to previous work-study of 120cc engine. This part deals with effect of Transient Thermal Analysis i.e. Temperature and Total Heat Flux on the different parameters of engine as mentioned above. So, in the continuation with previous work, the Intensification of the temperature and Total Heat Flux is studied on the Crown of the piston cylinder air-cooled and constant speed with Temperature range 25°C to 2000°C and Stagnant Water – simplified case with film coefficient 1.2e-003 W/mm2°C as Convection. Now, the results of Mexican Hat 120cc obtained in previous paper is compared with Transient Thermal Factors and Analytical study continues to finalize the improvement for better efficiency and performance of selected piston bowl geometry. UG-NX 9.0 parametric software is used for design and Transient Thermal Analysis Ansys 15.0 is used for Analysis, Tangential Slottes.
