| Summary: | This method is used to compute the Gorlov turbine model of two dimensions
using linear triangular elements. The model is assumed to be a viscous
incompressible fluids system and have the continuity and Navier – Stokes
equations as the governing equations.
The codes are built under MATLAB version 7 and run using Celeron 1.7 GHz
computer with 512 MB memory. The program was verified using system of
sphere in incompressible fluid with Reynolds Number 40. The codes were used to
get the flow of 10000 Reynolds fluids for Gorlov turbine.
The result of computation for 40 Reynolds fluids is in agreement with other works.
The boundary layer appeared around wall of object. The pattern of the change of
vertical and horizontal velocities pointed it out. Out of the layer, the fluids flow as
the far flow.
The computation result of Gorlov turbine model does not show the wake effect
between blades. The distances of blades which are far enough are the reasons.
CDs (Drag Coefficient ) and CLs ( Lift Coefficient ) of the Gorlov turbine blade
profile ( NACA 0017 ) bring non zero Torque. It shows that this turbine is selfstarting
as claimed by the inventor. |
