Abstract

To design this system, the analysis of velocity, pressure and temperature distribution in the gap between hydro viscous drive friction discs is important. In this work, there are two dics – one fixed and other one is rotating and fluid flows between two discs for measuring the velocity of it at constant speed of rotating by using the experimentally setup. This results compare with the simulation result for the same data which shows improve velocity of fluid by experimentally setup than simulative result. Also measure velocity on various types of dics which is used in hydro viscous drive system i.e. cocentric circular slotted disc or radially slotted disc. In present work, it is found that increase in speed increases the fluid velocity. Increase in speed from 100rpm to 200rpm for flat surface disc and water as a fluid, the overall increase in fluid velocity is 45.78% while for oil as a fluid, the overall increase is 39.86%.For disc with concentric circular slots and water as a fluid, the overall increase in fluid velocity is 44.2% while oil as a fluid, it is 44.29%.And for radially slotted disc and water as a fluid, the overall increase in fluid velocity is 41.91%,while for oil as a fluid, it is 51.29%. The experimental results shows that increase of gap from 5 mm to15 mm contribute into increase the velocity. The overall increment for flat surface disc when water is used as a fluid, is 47.42%, while oil as a fluid, it is 29.51%.Similarly for disc with concentric circular slots, overall increase in velocity when water as a fluid is 51%, while oil as a fluid, it is 22.92%.And in case of radially slotted disc overall increase in velocity, when water as a fluid is 47.74%, while oil as a fluid, it is33.06%. The results infers that among three surface geometries, the flat surface geometry gives comparatively higher velocity and followed by concentric circle slot geometry and radial slot geometry. For 5mm gap and water as a fluid, the overall decrease in velocity is 21.14%, while for oil as a fluid, it is 18.07%.Similarly for 10mm gap and water as a fluid, overall decrease in velocity is 26.89%, while for oil, it is 21.64%.And in case of 15mm gap, when water is used as a fluid, overall decrease in velocity is 21.06%, while for oil as a fluid, it is 17.08%.
