Myring equation

WebJul 10, 2015 · Myring [ 9] established the Myring hull profile equation to represent the lowest drag coefficient for a given ratio between the length and maximum diameter of a torpedo-shaped submersible. This equation has primarily been applied to the design of the external shape of a torpedo [ 7 ]. WebData from experiment is analyzed to obtain the CP for each model showing that the highest CP is achieved by three-bladed rotor with θ=10°. Furthermore, the minimum and the maximum value of θ as parameter control are discussed and they can be used as a good reference for further development of Bach-type blades for the Savonius turbine.

WebJan 28, 2024 · The CAD model is done in Rhino 7 and I have made Grasshopper definitions of both the Myring and Series 58 equations. So it is fairly easy to generate different hull forms and compare to plans. So far I've not gone much further with the Series 58 than inputting the parameters from the shapes described in Gertler's 1950 paper. WebJan 23, 2024 · In our paper the Savonius wind turbine blade geometry was based on the so-called Myring equation. The primary objective of this paper was to increase the power coefficient by modelling the effect of the wind on the turbine blade. For the sake of simplicity, a 2D cross-sectional area was investigated in the simulation with ANSYS CFX …
