Abstract: Mass conservation equation is employed to study the time evolution of the mass of oil in a reservoir, according to the actual mass flow rate of extraction. It is also possible to define the critical mass flow rate of ...

Abstract: Advanced performances in nanospacecraft are typically associated with high onboard power availability, requiring deployed solar arrays. Nanospacecraft geometrical and weight constraints do not allow the use of reversible ...

Abstract: A microscopic vision is presented of a dual model of liquids (DML) starting from a solid picture. The task is accomplished first by showing how a series of experimental evidences and theoretical developments on liquid ...

Abstract: The present work investigates mass conservation equations in turbulent flow between parallel plates with variable mass diffusivity. Species conservation equations are relative to the average ...

Abstract: The aim of this work is the performance study of a polimeric electrolyte membrane stack. Extreme conditions of temperature and relative humidity, such as those that may be found in practical ...

Abstract: Unsteady and steady flow in a cylindrical chamber with a rotating cover has been studied for two Reynolds numbers and three aspect ratio values. The structure of the velocity and pressure ...

Abstract: This paper describes the design, construction, and performance of a cut‐and‐cover diversion conduit, which required applying some unconventional design concepts. The reasons for selecting a cut‐and‐cover conduit instead ...

Abstract: The success of the world-renowned bus rapid transit (BRT) in Curitiba, Brazil, is based on the interdependence of public transport, road system hierarchy, and land use regulation. Notwithstanding the consolidation of this ...

Abstract: The use of fiber-reinforced polymer (FRP) reinforcement is a practical alternative to conventional steel bars in concrete bridge decks, safety appurtenances, and connections thereof, as it eliminates corrosion of the steel ...
