Mathematical and Simulation Modelling of Moisture Diffusion Mechanism during Plastic IC Packages Disassembly

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Mathematical Modelling of Moisture Induced Panel Deformation

Mathematical modelling, moisture diffusion and specific energy consumption of thin layer microwave drying of olive pomace

In this study, the effects of microwave drying power on drying kinetics, effective moisture diffusivity, and specific energy consumption of olive pomace were studied at three different microwave power levels of 170, 360 and 510 W. Increasing microwave power resulted in a considerable decrease in drying time. The experimental data for moisture loss was converted to moisture ratios and fitted to ...

Research on Delamination Failure of Plastic Ic Packages in Components Reuse Processes

This paper describes the technological process for waste IC components reuse and studies its effect on the reliability of plastic IC components through some experiments. Results show that the high temperature thermal shock during printed circuit board (PCB) disassembly and appearance repair could lead to interfacial delamination and subsequent popcorn cracking in plastic IC packages. In the end...

New Mathematical Modelling and Dynamic Simulation of a Molten Carbonate Fuel Cell

In this study, a more accurate model of fuel cell of molten carbonate was also used that was determined input and output control variables and investigated the behavior of the system with respect to those variables. A more complete kinetic is also implemented for increasing the effectiveness of the presented paper. The input variables include fuel flow rate of cell which is methane and cell vol...
