Reduce the flow of the viscous friction and electromagnetic effects of unnecessary wear and tear, changing the parameters for flow.According to proposed scholar Adrian Bejan's entropy methods, and Professor Sheng-an Yang of the second law of entropy generation analysis in convective heat transfer research, the thesis analytically dimensionless rate of local entropy generation number in forms of Eckert ,Prandtl number , magnetic parameters and angular parameters. The results showed that entropy generation will increase with the inclined angle that is reducing angle will help reduce the rate of entropy generation. Besides, the study also demonstrated that the entropy generation rate increases with increasing magnetic parameters due to the applied magnetic field.
