Dehydration is one of the methods that would extend the shelf life of mushrooms. Dried mushrooms can be used in many different types of products. Furthermore, elevated temperatures during drying enhance enzymatic reactions that can result in improved flavor of dehydrated mushrooms. This study aims to model the dehydration of mushroom using finite element modeling (FEM) taking into account of ...

Phase gratings are used in many applications owing to their high transmission and thus higher diffraction efficiencies. COMSOL is based on finite element modeling and is chosen for 2 reasons; firstly, because it can handle complex 2-D and 3-D geometries and secondly, it can handle the vector nature of these structures. The objective of the design is to compare the results of a commonly used ...

The present work aims to develop a blood pressure sensor using MEMS/NEMS technology. A normal blood pressure detector is used externally, but this work mainly aims for designing an implantable nanotube based sensor for continuous monitoring of blood pressure. The use of COMSOL Multiphysics 4.1 acts as a good platform to develop a nano tube based sensor design by using the MEMS module. The main ...

The micro machining technology that emerged in the late 1980’s can provide micron sized sensors and actuators. Actuators are used for the transformation of non- mechanical input energy into mechanical output energy. There are many types of micro- actuation mechanisms, most commonly used are piezoelectric, magnetic, thermal, SMA, electrochemical, electrostatic actuation. Electrostatic actuation ...

Electromagnetic forming (EMF) is a typical high speed forming process using the energy density of a pulsed magnetic field to form workpieces made of metals with high electrical conductivity like e.g. aluminium. This forming process can be very advantageous as compared to conventional forming process. EMF process is simulated by a commercial finite element analysis (FEA) solver, COMSOL ...

This paper presents the design and simulation of high sensitivity and fast response capacitive humidity sensor. Generally, the capacitive humidity sensor is made up of parallel electrode, the upper electrode being a grid with various line width and line spacing. A model is simulated using COMSOL Multiphysics. High sensitivity and fast response of the model is optimized by varying the ...

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in rotary kiln with limestone feed to get the desired temperatures. Microwave heating of limestone is proposed to ...

Valveless micropumps have the advantage of being composed of least number of movable parts and hence can be used for long-term drug delivery applications. Their working principle is based on reciprocal forcing of fluid by an actuator through diffuser/nozzle elements generating a rectified mean flow. Micropumps based on different actuating mechanisms have already been designed and fabricated ...
