Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which among other components consists of a heating section for cooking kheer. The present study investigates the CFD ...

The successful implementation of a high-efficient latent heat storage system necessitates an appropriate experimental approach to investigate and quantify the variations of the Phase Change Material (PCM) thermal properties caused by its aging, as well as its potential demixing induced by cyclic freezing and melting. In this paper, we present a concept for the PCM characterization. The proposed ...

Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis to cover a broader range of coolant flow. In addition, this new calculation expands the analysis much further ...

An FEA model of a steady state thermal interface material characterization apparatus was created in COMSOL Multiphysics 4.2a. This model was then fitted using three convection heat loss coefficients and the conductance of the TIM layer to a set of experimental measurements made using a steady state apparatus. It was shown that the model successfully matched the measured temperature values and ...

All-solid-state batteries are among the next generation battery concepts that are currently being envisaged among both the international research community and industrial electronic vehicle producers. In addition to a long lifetime of more than several thousand cycles and intrinsic safety, applying solid electrolytes offers a high energy density due to larger electrochemical windows. Aluminum is ...

Based on the heat transfer and seepage theory in porous media, a 2D cross section of a horizontal AGF project is selected and a numerical model is set up, which is based on full coupling of temperature and flow fields by combining physical interfaces of Darcy's Law and Heat Transfer in Porous Media. The simulation results show that freezing wall appears in an asymmetrical shape as the ...

Plate fin-tube heat exchangers are used extensively in heating, ventilating, and air conditioning, process engineering, and refrigeration systems. They have a high degree of surface compactness. Substantial heat transfer enhancement is obtained as a result of the periodic starting and development of boundary layers over interrupted channels formed by the fins and their dissipation in the fin ...

The most common way to exchange heat with the bedrock in Ground Source Heat Pump (GSHP) applications is circulating a fluid through a U-formed closed loop in vertical boreholes drilled several tenths of meters into the ground. This study presents and compares the results of eight cross sectional U-pipe Borehole Heat Exchanger configurations. Values from recent experimental temperature ...

This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of several state variables, such as pressure, temperature, heat, velocity vector. In the second part, COMSOL heat ...
