Vapor-compression technology has been the dominant refrigeration technology for decades, due to its scalability, relatively compact size, high reliability, and other attributes. However, the refrigerants used in vapor-compression equipment have detrimental effects on the global ... En savoir plus

A model for the conjugate simulation of heat and moisture transfer inside porous materials and fluid domains is implemented in COMSOL Multiphysics®. The results of this model are compared with those obtained through a simplified approach: the line-source approach. The models are both ... En savoir plus

In recent times, the major concern in the area of microelectronics is efficient heat transfer which will improve the operating characteristics of the device as well as minimize its failure rate due to induced overheating. The removal of excess heat from the system can be done by ... En savoir plus

This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which ... En savoir plus

Magnetic levitation systems have been studied in the context of high-speed transportation as maglev trains, high speed machinery as magnetic bearings, and other similar engineering applications. In this paper, a three dimensional arbitrary shaped object is modeled and analyzed through ... En savoir plus

INTRODUCTION: Point-Of-Care (POC) and home care systems are of growing importance in biotechnological and medical applications [1]. These devices allow health monitoring directly at home or at the doctor’s office. Portability, low-cost, easy handling and compatibility with telemedicine ... En savoir plus

Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... En savoir plus

Significant submarine mineral deposits form when hot, metal-laden, saline fluids emerge onto the seafloor and mix with ambient seawater. Resulting density changes of fluid mixtures can trigger fluid buoyancy reversals, brine pool formation, and metal accumulation (Figure 1). While some ... En savoir plus

This paper demonstrates experience of using the COMSOL Multiphysics® transport phenomena models in design practice, particularly at the early stage of design when there is might be too many possible design suggestions relying on the shell balance equations, and engineering intuition. ...

In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our ... En savoir plus
