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 ...

The tunable capacitor (variable capacitor) is one of the most important and components in filters, Phase shifters, VCO etc. A tunable capacitor can also be built using electro – thermal actuating mechanism. Compared to electro static, tunable capacitors actuated by thermal actuators have several advantages like lower driving voltages. The performance of thermal actuator becomes a key factor ...

In the model silicon nanorods are designed as cantilever array and coated with thin film of aluminum or aluminum nitride, to be characterized, thus, adding a detectable mass and altering the cantilever resistance to bending. The simulated results show that when films of different thickness are placed on the cantilever, there is a corresponding change in the resonant frequency and the ...

A MEMS based Knudsen’s pressure gauge working in the range of 1e-5 mbar to 10 mbar is designed and simulated in COMSOL. The working principle is based on Knudsen’s forces that arise when two plates are held at different temperatures and their separation is comparable to the mean free path of the ambient gas molecules. The forces change the separation between the plates and capacitance between ...

A three Dimensional model of the PEM Fuel cell is implemented using COMSOL Multiphysics and the channel width is varied to study the performance.Effect of channel width on the performance of the cell is studied by varying the width of the channel and keeping channel width to rib ratio constant at 1. Rib width is the width of the GDL area which is not covered by the channel. All other parameters ...
