In this paper, we develop and analyze a standard piezoacoustic Tonpilz-transducer model for underwater acoustics in Comsol by addressing the attendant piezoelectric and pressure acoustic multiphysics phenomena. Transducer properties that are studied and characterized are the center ... Read More
Effect of Bed Diffusion and Operating Parameters on Char Combustion in the Context of Underground Coal Gasification
Char combustion is one of the most important reactions in the process of Underground Coal Gasification (UCG). Experiments are performed in a boat reactor under near isothermal condition to demonstrate effects of heat and mass transfer and bed diffusion through ash layer. To obtain a ... Read More
Finite Element Modeling of Freezing of Coffee Solution
Freeze-drying is a popular method of producing shelf stable particulate products and is of particular value for drying thermally sensitive materials (volatiles and biological based), which can be heat damaged by higher temperature methods, such as spray-drying. Porous structures are ... Read More
Electrowetting-On-Dielectric Induced Droplet Actuation in M x N Array of Electrode
Digital microfluidic system based on EWOD (electrowetting-on-dielectric) technology can perform different fluidic operations on the same electrode array by simply modifying control software. One of the major challenges in EWOD device is to address each electrode individually in M x N ... Read More
