Recently, the cooling process for electronics components has attracted many researchers and several techniques for improving the cooling efficiency and heat transfer rate have been demonstrated. One of the best efficient techniques is the introduction of a synthetic jet and the modification of...

During the past few years, the plant nursery sector has drastically minimized its carbon footprint by using geothermal systems for heating rather than fossil fuel. This study aims to define the temperature range inside a greenhouse by means of a multiparametric analysis, with regard to several...

In this paper, conditions of work, special features and problems of boilers with catalytic fluidised bed are described. The specific conditions, when the catalyst layer remains stationary and granular or becomes spouting, are also considered. There are some main zones in the catalytic boilers...

A novel passive space conditioning configuration is presented, integrating a Solar Collector System, Underground Storage Tank and Novel Heat Exchanger. This Underground Solar Thermal Heat Exchanger (USTHE) provided improved sensible heating/cooling of air by employing a Novel Heat Exchanger...

In recent years, the lattice Boltzmann method (LBM) has become an alternative and attractive approach to simulate numerous fluid flow problems. A colloidal mixture of nano-sized particles in a base liquid called nanofluid, which is the new generation of heat transfer fluid for various heat...

Nowadays, computer models have contributed to a better understanding and solution of long standing practical combustion problems in HCCI (homogenous charge compression ignition) engines. In this study, a new multi zone model is developed for HCCI engines simulation. Model contains four different...

The subject of Magneto-hydrodynamic attracted the attention of many research workers in view of its applications to physics, medicine and engineering. The interest in these types of problems stems from the possibility of managing the thermal behaviour or to control the viscous property of the...

A novel GAHP-TSU (gravity-assisted heat-pipe thermal storage unit) is presented, in which the composite granular solid–liquid PCM (phase-change material) is piled up as the porous-medium layer. The composite PCM, which melts over a temperature range of 200–250 °C, is composed of a mixed...
