Real Fluid Simulation for Determination of Engine Oil Viscosity

Viscous characteristics of a Newtonian fluid is described by the dynamic (absolute) and the kinematic viscosity coefficients. The dynamic viscosity coefficient expresses the required applied force per unit area of the one laminar plane of the fluid in order to move it with respect to the adjacent, at an unit velocity. The Kinematic viscosity coefficient is the ratio of dynamic viscosity coefficient and the density of the fluid. This paper presents two simple software procedures for determination of the kinematic viscosity coefficient of real fluids. In addition, the laboratory experimental measurements of some oils’ viscosities were done to confirm the proposed procedures, and are presented in the paper as well. The authors intended for the procedures to be used for educational purposes at the college level entry.
