Direct air-cooling condenser has attracted significant attention in the last decade due to the employment of Rankine-cycle based power plants from renewable (e.g., concentrated solar) or traditional (e.g., coal) heat sources in water-scarce areas. The opti ...
This study reports the results from an experimental comparison of two cooling systems. The studied systems were a radiant cooling system (radiant ceiling panels and mixing ventilation), and a combined radiant and convective cooling system (combination of a ...
This study reviews the current state of the art and the current research activities of high temperature heat pumps (HTHPs) with heat sink temperatures in the range of 90 to 160°C. The focus is on the analysis of the heat pump cycles and the suitable refrig ...
This study reviews the current state of the art of high temperature heat pumps (HTHPs) with heat sink temperatures of 90 to 160°C. The focus is on the analysis of heat pump cycles, suitable refrigerants, and the operating ranges of commercially available H ...
The channel-to-channel heat flux variation was studied by solving numerically the conjugate, three-dimensional, transient heat transfer problem of louvered fins bounded by multiport aluminum plates. Two different multiport plate configurations (A and B) we ...
Radiant heating and cooling systems have the potential to save energy and are widely used in zero net energy buildings. Their positive and negative impacts on indoor environmental quality and, in particular, thermal comfort compared to all-air systems are ...
Energy consumption in industrial processes is mainly in the form of heat. Thus, heat recovery is one of the main focuses in industrial energy efficiency problems. Heat integration (HI) techniques have been studied extensively to solve such problems. One of ...
Motivated by the dynamics of microbubbles near catalytic surfaces in bubble-powered microrockets, we consider theoretically the growth of a free spherical bubble near a flat no-slip surface in a Stokes flow. The flow at the bubble surface is characterised ...
In this paper we develop new methods for studying the convergence problem for the heat flow on negatively curved spaces and prove that any quasiconformal map of the sphere Sn−1,n≥3, can be extended to the n-dimensional hyperbolic space such that the heat f ...
Next-generation High-Performance Computing (HPC) systems need to provide outstanding performance with unprecedented energy efficiency while maintaining servers at safe thermal conditions. Air cooling presents important limitations when employed in HPC infr ...
