The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is based on the results obtained with a two-dimensional modelling approach. For both packs, the simulations ...

In recent years the thermal behavior of electric machines is an attractive research topic. Due to the complexity of the problem, several approaches that exploit FEM analysis have been developed and presented in literature. In this research a 3D thermo-fluid dynamic simulation of an electric machine equipped with rubber belts directly applied on its shaft has been performed through COMSOL ...

This paper explores the complexities of a dragonfly's flapping wing motion. It includes the literature as well as analytical results using simulations done in COMSOL Multiphysics® software. The study depicts the Fluid-Structure Interaction of the 2D wing (airfoil) with air, governed by Naiver-Stokes equations. The wing follows mathematical functions and is given motion similar to dragonfly's ...

This paper presents steady and unsteady computational results obtained from numerical solutions of the full two-dimensional governing equations for annular internal condensing flows in a channel. This is achieved by tracking the “sharp” interface while solving the flow fields using COMSOL Multiphysics® and MATLAB®. The unsteady wave simulation capability is used to predict heat-transfer rates ...

The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment while holes pull cells toward the surface and increase residence time on the surface increasing attachment rate.

Present study discusses a new method of how to apply numerical simulation in COMSOL Multiphysics® software to improve the accuracy of polymer melts viscosity measurements. The main emphasis is placed on evaluating the effects of entrance and exit geometry of a capillary rheometer on viscosity measurement. By combining experimental and COMSOL® simulation results, an accurate Bagley correction ...

This study presented the results of 3D unsteady CFD simulations to investigate the influence of adding a flat baffle plate at the entrance during the discharging operation on the flow behaviour, thermal stratification, and performance of a hot water storage tank installed in solar thermal energy systems. The CFD results showed that the plate modified the flow field close to the inlet jet, ...

The major steps in the beer making process are simple and with some skill, rather good brew can be produced using a common picnic cooler. First, grain (usually barley) is wetted and allowed to partially germinate before dried in a kiln (malting) Next, during mashing in a mash tun reactyor the malted grains are soaked in hot water in to extract the fermentable sugars and then rinsed slowly to ...

In boreholes nozzles have to be found advantageous to increase the infiltration rate of water into the subsurface ground. Studies and practice in the field shows that the infiltration of water into permeable aquifers can be improved, if the flow in the borehole is modified. Due to the nozzle the flow regime turns from linear to turbulent. CFD studies help to understand the physics of the ...

In magnetically confined fusion devices, electron cyclotron resonance heating (80-170 GHz) is characterized by a local RF-power deposition at the electron cyclotron resonance . A mm-wave RF Gaussian beam is launched from a dedicated antenna and propagates through the highly turbulent scrape-off layer (SOL) at the edge of the confined plasma. Turbulence in the SOL is characterized by ...
