The Design – Design Analysis for Gorlov Helical Turbine
| ANSYS Fluent
The Gorlov helical turbine (GHT) is a water turbine evolved from the Darrieus turbine design by altering it to have helical blades/foils. It was patented in a series of patents from September 19, 1995, to July 3, 2001, and won 2001 ASME Thomas A. Edison. GHT was invented by Alexander M. Gorlov, professor of Northeastern University.
The physical principles of the GHT work are the same as for its main prototype, the Darrieus turbine, and for the family of similar vertical axis wind turbines which includes also Turby wind turbine, aerostructure turbine, Quietrevolution wind turbine, etc. GHT, Turby, and Quietrevolution solved pulsatory torque issues by using the helical twist of the blades.
The helical turbine (Germany patent DE2948060A1, 1979) was originally invented by Ulrich Stampa (Bremen, Germany), engineer, author, and inventor.
In this analysis, it has been tried to analyze the simulation of Design Analysis for Gorlov Helical Turbine, using the ANSYS Fluent software.
Geometry & Grid
The geometry required for this analysis was generated by Ansys Design Modeler software. The meshing required for this analysis was also generated by Ansys Meshing software. The mesh type used in this analysis is unstructured. The total number of volume properties for shell & tube geometry is 7,513e+007 mm³.
In this analysis, the k-epsilon RNG turbulence viscosity model has been used to check the fluid flow, and also the Scalable Wall Function near the walls has been used.
In this analysis, the Cell Zone Condition for the design modeler part is defined by the Mesh Motion tab, and the gauge total pressure for the inlet is 700000 pa is given to the design modeler.
Discretization of Equations
Due to the type of heat transfer in this analysis, a Pressure-Based solver has been used to solve the equations and the Coupled Algorithm for the discretization of velocity and pressure has been used. The energy and momentum equations have been discretized in the second-order upwind.
The results are presented as velocity contours.
