The performances of thermal-concentrated solar thermoelectric generators (TEGs) at three different geometric types are investigated numerically to aid in designing practical devices. The temperature-dependent properties of the commercial thermoelectric material are taken into account, and an...

In this paper, we present a methodology for calculating the thermal efficiency of a pot on an electric stove using numerical simulations in ANSYS FLUENT®. The system domain was divided into three subsystems: electrical resistors, the air volume inside the resistors, and the pot. It was...

The big problems facing solar-assisted MED (multiple-effect distillation) desalination unit are the low efficiency and bulky heat exchangers, which worsen its systematic economic feasibility. In an attempt to develop heat transfer technologies with high energy efficiency, a mathematical study is...

It is indispensable for strengthening smelting process and controlling fine to understand metallurgical behaviors and mechanism of production process of aluminum holding furnaces. A CFD (computational fluid dynamics) compressive process model was developed and integrated with energy distribution...

A nonlinear Fokker–Planck equation is proposed for a system subject to different statistics (in the present study, the Gibbs–Boltzmann and Fermi–Dirac statistics) defined in different contiguous regions of space. We solved the time-dependent mono-dimensional equation numerically, and...

We present simulation results on a novel dew-point evaporative air conditioner which was designed based on a counter-flow closed-loop configuration consisting of separated working channels and product channels. The novel evaporative air conditioner is able to cool air to temperature below...

The supersonic separation is a novel technology in the natural gas dehydration for its compact design and fewer emissions. The other fascinating advantage is that the diffuser can convert kinetic energy into pressure energy to improve the energy efficiency. The mechanism of the pressure recovery...

This paper presents the findings from a multi-objective genetic algorithm optimization study on the design parameters of an underwater compressed air energy storage system (UWCAES). A 4 MWh UWCAES system was numerically simulated and its energy, exergy, and exergoeconomics were analysed. Optimal...
