This book considers the behavior of fluids in a low-gravity environment (e.g. spacecraft) with special emphasis on application in PMD (propellant management device) systems. Since PMD designs are not testable on ground and thus completely rely on analytical or numerical concepts, this book treats three different flow problems with analytical, numerical and experimental means. These problems are linked together by the same set of equations and boundary conditions.
