| Abstract | ||
| Transient thermal stresses in pipe wall due to coolant turbulent flow through pipe are investigated in this study with transient isothermal hot boundary in the external pipe radius. Three Different values of Reynolds are tested (3000, 5000 and 8000). Finite volume method was used to calculate the velocities and temperatures fields in the working fluid (air). Thermal resistance method was used to calculate the transient temperature distribution in the pipe wall and then the transient thermal stresses were calculated. Minimum thermal stress was located nearly in the mid plane of the pipe. | ||
