In this work we study numerically the 3-D turbulent natural convection in a partially heated cubic cavity filled with water containing metallic nanoparticles, oxides, and others based on carbon. The objective is to compare effect of addition nanoparticles studied also position partition heat exchange by type geometry, which can significantly improve design systems for better space optimization....

In Chinese hamster ovary cells and in normal and transformed rat embryonic fibroblasts, survival as a function of time at 42.4 degrees was dependent upon the rate of heating from 37 degrees to 42.4 degrees. Unexpectedly, the untransformed rat fibroblasts were more heat sensitive than were the transformed cells, and the protective effect of slow rates of heating upon survival at 42.4 degrees was...

Changes in the trypsin inhibitor activity (TIA) of faba beans (Vicia faba L. Major) were investigated after beans were soaked in distilled water, citric acid, and sodium bicarbonate solutions. The soaking solution was discarded. The effect of cookingsdiscarding both soaking and cooking solutionsswas also studied. Finally, a dry-heating process was examined. Soaking treatment produced a slight d...

Heat transfer and fluid flow due to buoyancy forces in a partially heated enclosure using nanofluids is carried out using different types of nanoparticles. The flush mounted heater is located to the left vertical wall with a finite length. The temperature of the right vertical wall is lower than that of heater while other walls are insulated. The finite volume technique is used to solve the gov...

The entropy generation during transient laminar natural convection in a square enclosure is numerically investigated. Two different cases are considered. The enclosure is heated either completely or partially from the left side wall and cooled from the opposite side wall. The bottom and the top of the enclosure are assumed as insulated. The Boussinesq approximation is used in the natural convec...
