This paper is to develop analytical models for the underwater capacitive micromachined ultrasonic transducer (CMUT) to understand its large deflection effect from the water pressure. To accurately model the displacement profile of the CMUT under the water pressure, Von Kármán equations and the perturbation method are employed to calculate the membrane deformation from a uniform pressure. The equations...
Square-shaped pneumatic conveying pipes are used in some industrial processes, such as fuel injection systems in coal-fired power plants and circulating fluidized beds. However, a little research has been conducted to characterize the gas–solid two-phase flow in a square-shaped pneumatic conveying pipe. This paper presents mathematical modeling and experimental assessment of novel non-restrictive...
