Hydrocooling is the process by which warm produce is chilled with water. The chilling of warm produce generates a negative pressure differential between the produce (warm) and (cold) water due to the condensation of water vapor inside the produce which forms a vacuum and can pull in contaminated water through an opening. A porous media based model of water infiltration was developed using a ...

The microwave heating and processing of heterogeneous material is usually simulated using a set of coupled PDE equations in an homogeneous medium. Nowadays it is possible to describe more accurately the process with a suitable description of the heterogeneities that is at the grain level. Many authors work with spheres (circles) to represent the grains but it is difficult to achieve an ...

The four foot diameter class A evaporation pan is used by the scientific community as the standard for determining evaporation rates for a number of purposes. The COMSOL Multiphysics® software provides the necessary tools to adequately develop synthetic estimates of evaporation values for input into hydrologic simulation models and other earth science applications. This paper presents ...

Power transmission through power cables installed in ventilated tunnels has been increasingly used worldwide and offers a complex thermal environment. These cables are placed on supports or fixed close to the tunnel walls. Established correlations currently in use have been deduced from a non-fully developed turbulent flow and the effect of the proximity to a tunnel wall is not accounted for ...

Vehicles with battery as energy storage fascinate more and more people. Meanwhile, more questions are surfaced – How to ensure a safe operation of the battery package? How long could the cycle life of a battery package reach? Can a battery package be operated in any environmental circumstance? All these questions are the driving forces of our work – development of the optimal battery packs for ...

This paper describes using thermal structural interaction to model the shrinkage behavior in cement paste under drying. An inverse method of combining the finite element analysis and the least-squares method is implemented to fit experimentally determined shrinkage in order to obtain material propertiesfrom the complex geometry used in the tests. The finite element model is created in COMSOL ...
Multiphysics Between Deep Geothermal Water Cycle, Surface Heat Exchanger Cycle and Geothermal Power Plant Cycle
International Centre for Geothermal Research, Helmholtz Centre Potsdam, GFZ German Research Centre For Geosciences, Telegrafenberg, Potsdam, Germany
Within the framework of Groß Schönebeck project in the North German Basin of Germany, multiphysics between deep geothermal reservoir, boreholes, heat exchangers and power plant is crucial to study lifecycle behavior of each component thereafter a later coupling to study lifecycle and recovery of the overall geothermal system. Study is divided into geothermal water cycle, surface heat exchanger ...

In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. Since the chemical reactions at the surface of the sensor material are functions of temperature. We simulate our µHeater design on a Buckled Cantilever Plate (BCP). Such structure allows the sensor to be suspended for thermal insulation. ...

High-power couplers working at 350 MHz for particle accelerator cavities are presently under development in the LEHIPA project at BARC. It is important to analyze RF losses on conducting surfaces and resulting thermal profiles. COMSOL Multiphysics® is used to study these coupled RF-thermal effects and estimate cooling requirements for these couplers. The RF loss on the copper conductors and ...

Radiant heating generally addresses all heat emission systems having a share of radiant heat emission greater than 50%, compared to a convector or fan coil where the heat is transferred mainly by means of convection. Recently, so-called infrared-heating systems are discussed as a cost-effective heating system. Relative small areas of typically 0.6 m x 1.2 m with temperatures up to 120 °C are ...
