... Abstract Hydrogen is an element that can be stored via phase change through compression or liquification by varying temperature and pressure, or through physical or chemical bonding. This study provides a closed-form transient temperature model of a spherical liquid hydrogen storage tank heated...

... takes up latent heat, has become crucial. However, two-phase systems have higher pressure drops than single-phase ones, which decreases overall efficiency. So being able to accurately predict the pressure drop is really important for efficiency and reliability. Currently available models for two-phase...

... electronic components. That is to say, there may be a positive or negative heat transfer through the electronic unit from the rest of the system. The first step in the model reduction process employed in this study involves removing regions distant from the unit of interest from the analysis model...

... flow physics. Eilmer is a structured/unstructured grid flow solver based on finite-volume discretization of the time-accurate compressible Navier-Stokes equations with validated turbulence models, finite-rate internal energy excitation, and chemical kinetics. The work first targets a validation case...

... and a preheating zone. Carbon fiber-reinforced matrix carbon composites are used as the inner and outer panels of the sandwich structural materials, while structurally designed metal grids are proposed as the core material. We establish flow, heat and mass transfer, and chemical reaction models to carry out...

.../fouling on polymeric heat transfer surfaces. In this work, we evaluate the performance of AGDD in terms of the water flux (permeate collected) and energy consumption (gain output ratio). A coupled heat and mass transfer model is developed to simulate brine concentration from a salinity of 70,000 mg/L up...

... or the critical condition of preventing molten salt from freezing. The effects of molten salt flow velocity, heat capacities of molten salt and pipe, dimensions of pipes, and the initial temperatures of salts and cold pipes are all correlated theoretically in the analysis through modeling of transient heat...

... furnaces with high efficiency and low cost, thereby enabling the development of condensing furnaces without the use of expensive corrosion resistant materials in the heat exchanger. A three-dimensional (3D) computational fluid dynamics (CFD) model has been developed to evaluate the heat transfer...

Published modeling assumes that the human eyeball is at a constant temperature, mostly at 37 °C. Understanding the exact temperature...

... The spiral-wound heat exchangers are widely used in industrial applications, but the mechanism of flow and heat transfer in shell side has not been clarified yet. A three-dimensional model is developed based on the FLUENT software in this study, with emphasis on quantifying the effects...
