In this research, the second Law for free convection of air flow in L-shaped enclosure with a heat generating body, is numerically studied. In this study, the continuity, momentum and energy equations are solved, using a finite volume method and SIMPLER algorithm. By positioning the heat generating body at three different locations inside the enclosure for three aspect ratios of enclosure in va...
Abstract—Conjugate natural convection in a differentially heated square enclosure containing a polygon shaped object is studied numerically in this article. The effect of various polygon types on the fluid flow and thermal performance of the enclosure is addressed for different thermal conductivities. The governing equations are modeled and solved numerically using the built-in finite element m...
The macroscopic, three-dimensional surface layout geometry of an enclosure apparently provides a different contribution for spatial reorientation than the geometric cues associated with freestanding objects arranged in arrays with similar geometric shape. Here, we showed that a unitary spatial representation can account for the capability of animals to reorient both by extended surfaces and dis...
This paper reports results of a study regarding the activities of nano structure Mn/γ-Al2O3 and γ-Al2O3 catalysts for oxidation of 2-propanol (as a model of volatile organic compound). Nanostructure of catalysts was revealed using XRD, SEM and TEM techniques. Catalytic studies were carried out in U-shaped packed bed reactor under atmospheric pressure and at the reaction temperature of 150- 500°...

Rats were trained to search for a food reward hidden under sawdust in the center of a square-shaped enclosure designed to force orientation on the basis of the overall geometry of the environment. They were then tested in a number of enclosures differing in shape and in size (rectangular-, double-side square-, and equilateral triangle-shaped enclosures). Results showed that rats transferred the...
This paper is concerned with the analysis and design of an integrated passive and active control system for reducing the haul truck noise. By using a passive enclosure with two open ends and fiberglass inner surface, a three-dimensional noise radiation problem of the engine noise is shaped to a simple problem of noise radiation from the open ends above 200 Hz. Below 200Hz where the transmission...
