By William T. Sha

William T. Sha first proposed the radical porous media formula in a piece of writing in Nuclear Engineering and layout in 1980. the radical porous media formula represented a brand new, versatile, and unified method of remedy real-world engineering difficulties. the unconventional porous media formula makes use of the idea that of quantity porosity, directional floor porosities, disbursed resistance, and disbursed warmth resource and sink. so much functional engineering difficulties contain many complicated sizes and styles of reliable inner constructions whose dispensed resistance is most unlikely to quantify appropriately. the concept that of directional floor porosities gets rid of the only reliance on empirical estimation of the allotted resistance of complex-shaped constructions frequently fascinated with the research. The directional floor porosities therefore significantly increase the solution and modeling accuracy and facilitate mock-ups of numerical simulation versions of genuine engineering platforms. either the continuum and standard porous media formulations are subsets of the radical porous media formula. additionally, fluid-structure interactions are explicitly accounted for during this formula.
