Analytical Model of Fluid Flow through Closed Structures for Vacuum Tube Systems

An analytical model is developed to evaluate airtightness, which is one of the most important requirements of vacuum tube transportation systems. The main objective of the model is to anticipate the pressure inside a closed structure, which initially decreases and then rises with time owing to the i...
