In the present study, the power consumption in a stirred vessel by two-blade impeller has been investigated. 3D finite volume based computational fluid dynamics (CFD) simulations have been carried out. The tank used has a cylindrical shape with a flat bottom. The liquid height was kept equal to...

The use of double skin facades (DSF) in the building sector and its thermal benefits have been widely studied numerically over the last 30 years. These modelling and simulations are based on different typologies, which have evolved altogether with the available computational resources. The...

A three-dimensional (3D) numerical model is proposed for natural state simulation of the Las Tres Vírgenes (LTV) geothermal system from emplacement and cooling of the heat source. A conceptual model of the LTV volcanic system was developed considering tectonic regime, structural geology,...

This paper develops an inverse problem approach to optimize the geometric structure of TECs (thermoelectric coolers). The approach integrates a complete multi-physics TEC model and a simplified conjugate-gradient method. The present TEC model couples the heat and electrical conductions and...

Air-breathing engines are utilized in the hypersonic regime through thermal integration of the fuel into the propulsive cycle, which improves the efficiency by recovering thermal energy from the freestream and the aeroshell. The classical efficiency figures based on First Principle analyses are...

This paper presents the evaluation of the performance of a ground source heat pump system monitored plant providing heating/cooling to an office building located in the Universitat Politècnica de València in Spain. The system was designed using GLHEPRO software and it has been monitored since...

The lower sub-aquifers of the Mediterranean coastal aquifer of Israel, at the Palmahim area, are hypothesized to be laterally blocked to connection with the sea, and thus to seawater intrusion. This is mostly due to the detection of fresh water bodies at these sub-aquifers. This study examine...

Water and thermal managements are the most important issue in the operation and optimization of proton exchange membrane fuel cell (PEMFC). A three-dimensional, two-phase, non-isothermal model of PEMFC is presented in this paper. The model is used to investigate the interaction between water and...

As a key component of flow batteries, the flow field is to distribute electrolytes and to apply/collect electric current to/from cells. The critical issue of the flow field design is how to minimize the mass transport polarization at a minimum pressure drop. In this work a three-dimensional...
