Fuel cells that utilize hydrogen are promising energy conversion units that have a high intrinsic efficiency. However there are operational difficulties in storing hydrogen. One way to alleviate this problem is to ...

Nowadays, the interaction between process design and control has become the focus of research and development, because not always the best process design features the best dynamic performance, with implications in the ...

We analyzed the thermal performance of louvered fin heat exchanger with equal and unequal louver pitch which continuously increased by 20% from air inlet area to the redirection region and difference of thermal performance ...

In this work, nanofluids were prepared using commercial Cu nanoparticles and a commercial Heat Transfer Fluid (eutectic mixture of diphenyl oxide and biphenyl) as the base fluid. This fluid is used in Concentrating Solar ...

This paper presents a performance analysis and optimisation of a granular bed heat recuperator for thermal energy storage and recovery. Simulating the flow processes in the bed, the study develops a transient three-dimensional ...

The safety analysis of research reactors includes simulations of selected cases classified by the International Atomic Energy Agency (IAEA), since the simulations are performed using validated nodalizations and internationally ...

Rapid mixing in micro-channels plays a significant role in the chemical, biological and medical fields. The majority of microfluidic applications is encountered in very low Reynolds number regime. Thus, two reactive fluids ...

The use of high concentration ratio parabolic trough systems is emerging as one of the ways to further reduce the cost of energy from these systems. This paper reports on the thermal efficiency of a parabolic trough ...

Nanofluids are defined as dilute suspensions with solid particles smaller than 100 nm. Nanofluids present some important advantages over the conventional colloidal suspensions such as high stability, reduced particle ...

In this paper we propose a mathematical model with tensorial analysis for a single cavitating microshell bubble immersed in a newtonian liquid, excited by an ultrasound field. We obtain a system of nonlinear differential ...
