Internal flow analysis of bladeless turbine

Bladeless turbines are being more and more popular in those applications such as bio-fuel power generation systems, heat recovery systems, co-generation systems, solar energy systems and waste heat recovery systems. A mathematical model based on continuity equation and Navier-Stokes equations has been established to describe the operating processes of incompressible fluid in a Tesla bladeless turbine and analysis were carried out to internal flows; moreover, those influences on the turbine torque, power and efficiecy were emphatically investigated as for various key parameters. It shows that our calculated results and those experimental data from literatures are in relatively good agreement so that our mathematical model may be used to calculate those key parameters (such as efficiency, torque and power) of Tesla bladeless turbines. Therefore, this mathematical model shall be used for design and optimization of Tesla bladeless turbines.
