Compressibility of granular fluids

WebAug 1, 2024 · The elasticity of the system adds up to the total compressibility for each separate component in a hydraulic system (Bulk Modulus is reduced). Even if the hydraulic fluid gives the dominant contribution to the effective bulk modulus, the contributions from other system elements (pipes, sealings, valves, flexible hoses, etc..) may be significant … Webmodifying compressibility of the pore fluid in the numerical platform.

Webadding compressibility effects would ‘greatly regularize the equations’. Granular flows are indeed prone to dilate or contract in response to deformation. In the collisional limit, the volume occupied by granular flows depends directly on the granular temperature, which itself is a function of the imposed shear, thus allowing WebCompressibility of granular fluids Cite as: Phys.
