Metal contaminants and organic pollutants are affecting aquatic environments in urban and industrial zones. Mangrove trees are capable of absorbing metal ions and organic pollutants. To estimate the remediation potential, a two dimensional model of water and substance flow in the soil ... 詳細を見る

The paper aims to clarify some aspects of the gases hydro-dynamics within the twisted conduct of heat accumulation stoves (ceramic-refractory stoves) downstream the combustion chamber. Both Comsol laminar and k-e turbulent models have been used in case of straight and curved pipes with ... 詳細を見る

A microwave heating model coupled with heat, mass, and momentum transfer is needed to fully understand the microwave heating process. In this study a comprehensive 3D model was developed for studying the interaction of microwave with the food. The model includes physics of Maxwell’s ... 詳細を見る

Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this ... 詳細を見る

Tetrafluoroethylene (TFE) is a gas widely employed in industry, which can under specific circumstances experience an exothermic dimerization to octafluorocyclobutane. If the heat generated by this reaction cannot be dissipated to the surroundings, the temperature inside the reactor will ... 詳細を見る

Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML ... 詳細を見る

High-intensity discharge (HID) lamps are energy-efficient light sources with excellent color qualities. A three-dimensional model of a low-wattage lamp, which includes plasma, electrodes, and burner walls, was developed in COMSOL Multiphysics®. Most parameters appearing in the coupled ... 詳細を見る

Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main ... 詳細を見る

This paper presents the simulation of exhaust gas heat recovery system for an automobile using COMSOL Multiphysics®. A double pipe heat exchanger is modeled in which the tube side medium is the hot exhaust gas and the shell side medium is water. The problem is divided into three parts i ... 詳細を見る

Cross-flow around a group of cylinders is a very common phenomenon in engineering, such as flow around heat exchanger tube arrays. The cross-flow-induced vibration might cause a reduction of equipment life and might even lead to the occurrence of severe accidents. Hence, it is necessary ... 詳細を見る
