The article is focused on the mathematical simulation of temperature influence shear stress during mineral oil flow. rotary rheometer used to measure stress. It works principle torque measurement when spindle rotates in container with measured liquid. rotating together forms hollow cylinder which filled by oil. evaluated for various temperatures. software ANSYS Fluent evaluate partial numerical...

The transient response of a hollow finite cylinder with radial and axial material inhomogeneity to a pulse of short duration is analyzed. The problem is solved in two steps. Radial inhomogeneity is treated first by dividing the cylinder into coaxial segments each with a constant modulus E which is allowed to vary from segment to segment. Transfer matrices relating variables at the two radial in...

In this paper, the classic coupled poro-thermoelasticity model of hollow and solid cylinders under radial symmetric loading condition is considered. A full analytical method is used and an exact unique solution of the classic coupled equations is presented. The thermal and pressure boundary conditions, the body force, the heat source and the injected volume rate per unit volume of a distribute ...

Hollow cylindrical flow mixers achieve a homogeneous mixture with less pressure loss and higher momentum. However, the low volume of mixer due to hollow creates high effects mechanical stresses on mixer. In this study, formed by considering thermal fluids in conical cylinder at different temperatures were examined. The effect taper angle has been studied. examinations carried out using finite e...
