2D-modeling of arc welding in butt-joint configuration was performed in this study considering thermal-structural interactions. Thermal behavior was modeled in COMSOL Multiphysics® using the Heat Transfer Module with weld heat input as a Gaussian pulse whereas structural behavior using ... Mehr lesen
This paper deals with a numerical investigation on sliding door and people moving effects on the indoor climate of a standard ISO5 class OT with an ultraclean air filter system and a total ceiling unidirectional diffuser. A simple method to analyze the effects on the OT climate by ... Mehr lesen
Piping is a kind of internal erosion that occurs under water retaining structures lying on a sandy soil. In an attempt to reproduce the growth of erosion channels in sand, a small scale physical model has been set up in the laboratory and a finite element model that reproduces the ... Mehr lesen
This contribution is devoted to the mathematical modeling of the AC electroosmotic micropumps in COMSOL Multiphysics and Matlab. The mathematical model involves the microchannel surroundings and several AC-voltage driving modes. The weak form has been used for handling singularities and ... Mehr lesen
The classical optimization method has been applied to many design problems for electromagnetic systems. One of its major difficulties is related to meshing problems arising from shape modifications. In order to circumvent these kinds of technical difficulties with moving mesh problems, ... Mehr lesen
With the advent of MEMS, transdermal drug delivery has been developed to increase skin permeability for drug transport. Various microneedle structures have been analyzed theoretically as well as through simulation using COMSOL Multiphysics®. Then computational fluid dynamics has been ... Mehr lesen
Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... Mehr lesen
A numerical investigation of the long-term performance of double U-tube borehole heat exchanger (BHE) fields, in the case of non-negligible effects of groundwater movement, is performed by means of COMSOL Multiphysics. Two time periodic heat loads, with a period of one year, are studied: ... Mehr lesen
This work talks on simulation of a ventilating structure for an industrial burner. The mathematical model is based on the frozen-rotor technique, and the numerical simulation is used for resolution of fluid dynamics equations for the air flow into the rotating wheel and into the static ...
