We consider the velocity autocorrelation function, vacf, or Cv(t) and self-diffusion coefficients, D, of steeply repulsive inverse power fluids (SRP) in which the particles interact with a pair potential, (r) = (/r)n. The Cv(t) are calculated numerically by molecular dynamics simulations....
Unless specified, fluids are air and water. (6-1)Qair=K1*V1‐Ven′ where K1 is a constant, V1 is the jet velocity at impact and Ve is the velocity at which air entrainment commences. Ve is termed the onset velocity or inception velocity. In dimensionless form, equation (6-1) ...

Porous structures or metal foams have the potential of the heat transfer enhancement by the thermal conductivity and heat transfer area increment. A similar effect could be created by the proper suspension of the highly conductive nano solid particle in the working fluids1. These types of fluids k...
Magnetohydrodynamics (MHD) is the physical-mathematical framework that is concerned with the dynamics of magnetic fields in electrically conducting fluids. Any movement of a conducting fluid in a magnetic field, B, generates electric currents, j. Each unit volume of liquid having j and B ...
For example, an oblique banding occurrence most probably indicates the vanishing initial solute concentration before the infiltration of acidic iron-bearing fluids. When the Fe-bearing fluid flow speed narrows to a limited region, the oblique patterns emerge due to the competing growth of orthogonal ...
