Thermal Stresses on a Reginal Cooling Plate

In this study, stresses and strains that occur on the surface of material are investigated for a flat plate that is made cooling as numerically and analytically. The cooling blowing ratios applied to the surface vary between 0.5 and 1.75. The cooling injection angle is 30 degrees with the horizontal. Plexiglas plate were used in experiments which done for analytical solution and numerical modelling studies. Air was injected to cooling zone at 57 o C and 77 o C. The results show that the cooling surface size varies with the blow ratio. In addition, the sizes of thermal stresses and displacements of surface set out that they are indicators of cooling.
