implicit constitutive theory must be used in the modelling of incompressible fluids with pressure-dependent viscosity and that it is not possible to obtain a lower-dimensional model for the pressure just by letting the film thickness go to zero, as in the proof of the classical Reynolds equation...

assumptions which must be made in order to derive the equations of “slow” [Reynolds number R = 0(1)], essentially nonisothermal [▽ ln T = 0(1)] flows of a gas as a continuous medium (Knudsen number K → O) in the case when the derivatives of the thermal Burnett stresses in ...
We consider the limit when domain thickness tends to zero and prove that the limit pressure satisfies the non-linear two-dimensional Reynolds lubrication equation. Furthermore, we prove a convergence theorem for the velocity and the pressure in appropriate function spaces....
where k’= proportionality constant taking in the reciprocal of the equation, we get, \(\begin{array}{l} – \frac{ db }{ dl } = \frac{ 1 }{ k’i } \end{array} \) integrating the above equation we also get, \(\begin{array}{l} – b = \frac{ 1 }{ k’ } in l _ { ...

Through a convenient mathematical approach for the Navier-Stokes equation, we obtain the quadratic dependence v 2 of the drag force FD on a falling sphere, and the drag coefficient, CD, as a function of the Reynolds number. Viscosity effects related to the turbulent boundary layer under transiti...
