The electric power generated by thermoelectric modules obviously depends not only on the nature of the modules but also on heat transfers on both sides of these modules. In addition to the improvement of the thermoelectric material and module, analysis of thermoelectric systems is equally...

Three-dimensional numerical simulations are performed to investigate the effects of nitrogen (N2) and sulfur dioxide (SO2) impurities on the solubility trapping mechanism of carbon dioxide (CO2) geological storage. Dissolved CO2 has been suggested to increase the density of the aqueous phase....

Numerical analyses are performed to study the fluid dynamic behaviours of the solubility trapping in the context of CO2 storage in deep geological formations. Dissolution of CO2 into the underlying brine increases the density of brine, leading to a gravitational instability. This instability...

In this paper, non-deterministic CFD (computational fluid dynamics) simulations have been performed to investigate the uncertain effects of stochastic boundary conditions on the aerodynamic performance of wind turbines. A NIPRC (non-intrusive probabilistic collocation) method is employed, which...

The mechanism of repetitive extinction-ignition dynamics for lean premixed hydrogen–air mixture is studied in a microchannel with prescribed wall temperature. In this dynamics, the reacting flow is affected by the wall temperature and leads to ignition near walls. The flame expands in both...

Tile drainage systems are sometimes not sufficient to provide favorable unsaturated conditions in the rootzone. These drainage systems then need to be supplemented with an additional high conductivity material in the trenches above the tiles or by implementing mole drainage. The HYDRUS (2D/3D)...

In order to make better air utilization in combustion chamber to improve the mixture quality, enhance combustion efficiency and reduce emissions, a new swirl chamber combustion system of DI (direct injection) diesel engines is proposed. The in-cylinder spray, mixture formation and combustion...

To investigate the cause of the increase in the unburned fraction when sub-bituminous coal is mixed with bituminous coal observed in previous experimental research using a 100 kg-coal/h-class coal combustion test furnace, numerical simulations of the mixed combustion of sub-bituminous coal and...

In the present study, phase change materials based on epoxy resin paraffin wax with the melting point 27 °C were used as a new energy storage system. Thermophysical properties and the process of melting of a PCM (phase change material) composite were investigated numerically and...
