Abstract Refrigerating compartment with and without shelves is designed for analyzing the air flow temperature distributions by using Simulation software Ansys work bench 14. Comparing results of inside refrigerating shelves. Here considered as obstacles refrigerator freezer a 2D rectangular enclosure one side assumed evaporator wall (cold wall) other Door (warm wall). Inside cabin takes natura...

The effects of natural convection with and without the interaction of surface radiation in square and rectangular enclosures have been studied, numerically and theoretically. The analyses were carried out over a wide range of enclosure aspect ratios ranging from 0.0625 to 16, including square enclosures in sizes from 40cm to 240cm, with cold wall temperatures ranging from 283 to 373 K, and hot ...

nowadays green house gases such as carbon have the most effect on global climate changes that can be decreased by plant and soil carbon sequestration of rangelands. livestock grazing has high potential to decrease or increase carbon storage. so this research investigated the effects of enclosure on plant carbon storage in rangeland of enclosure (shah tappeh-chah mahmood) and no enclosure (chiro...
