Semi-Analytical Solution of 1D Transient Reynolds Equation(Grubin’s Approximation)

0 Ratings

A Matlab code for calculation of a semi-analytical solution of transient 1D Reynolds equation using Grubin’s approximation. At first, the Reynolds equation is integrated analytically using Grubin’s assumptions with respect to spatial coordinate and further numerically integrated with respect to temporal coordinate. Solution is then compared to the analytical Grubin’s solution for the central film thickness.
