PERFORMANCE ANALYSIS OF BLADELESS TURBINE USING COMPUTATIONAL FLUID DYNAMICS
In this project an analysis of a bladeless turbine for a cogenerating micro-power plant is design. This project also has been done the computational analysis. In reference paper has been done the solution result of the theoretical analysis includes discussion and comparison with rough preliminary experimental data. In this project is done to change the parameters and increasing the efficiency of different cases bladeless turbine. Blade less turbine utilizes the concept of boundary layer for its working. They have existed in many forms over the past century ranging from hand held turbines to very big size. Some types rely on water jet as there prime source while others use compressed air, steams etc. There are currently some interests in developing bladeless turbine, as the bladed turbines had their own problems. Most were huge pieces of machinery with very narrow tolerances. If not built properly, blades could break or crack. This project covers all the analysis including the fluid flow analysis through the bladeless turbine. Numerical calculations of the flow in several bladeless turbine models are performed for a range of design parameters. Results of the investigations exhibit interesting features in the distribution of flow parameters within the turbine inter disck space. The efficiency of the bladeless turbine depends on many parameters, including pressure, temperature and velocity conditions, rotational speed of the rotor as well as on the number, diameter, distance between the disks and the state of the disk surface and, finally, on the number and arrangement of the supply nozzles. The calculated flow efficiencies of the investigated bladeless turbine models show that the best obtained solutions can be competitive as compared with classical small bladed turbines.
