run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
INTRODUCTION Thermal stress becomes larger in the baby than in the adult, when they are exposed in a cold environment (Belghazi et al., 2005). This is because heat exchange in the baby is larger than in the adult due to the larger ratio of body surface area to body mass. Heat transfer form the body is also one of important factors to determine the level of the body heat exchange. Therefore, dis...
The inclusion of complex obstacles within solar channels is the aim of this article. Two obstacles of the form ꞌ+ꞌ interlaced within a two-dimensional and rectangular channel are the subject of our study. The fluid is Newtonian, turbulent, incompressible and has constant properties. The Reynolds number varies from 12,000 to 32,000 with a constant temperature along the upper surface of the chann...
The proton temperature profile of the asymptotic solar wind plasma can be modified by four different physical effects: PdV work, external heat deposition, Q D , divergence of heat, q · , and collisional energy exchange with other species in the plasma. Suggestions in the literature that Q D heating is “required” to explain the proton profile have often been deduced while neglecting qp and ene...
