Heat Transfer Optimization of a Solar Radiation Concrete Oven for Rural Areas

I. Abu-Mahfouz [1], G. F. Mathews IV [1], M. J. Young [1],
[1] Penn State University Harrisburg, Middletown, PA, USA

The process of creating healthy food and drinking water typically requires electricity and fuel sources that are not available in rural areas. Africa has an abundance of solar radiation which when properly harnessed creates a viable heating source for cooking food and purifying water. ... Saiba Mais

Quantitative Assessment of Secondary Flows of Single-phase Fluid through Pipe Bends

Z. Kaldy [1], O. Ayala [1],
[1] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA

Single-phase fluid flow was simulated passing through various three dimensional pipe elbows. The simulations varied by Reynolds number, curvature ratios, and sweep angles and were all conducted using the k-ε model available in COMSOL Multiphysics® software. The intent of this research ...
