Abstract: A chemical energy storage and transportation system is conceived based on sulfuric acid decomposition and synthesis processes using hot oxygen as a vector. A thermodynamic assessment is carried ...

Abstract: Natural convection, radiation and conduction heat transfer in passive solar massive wall systems with fins attached to the heated surface and without glazing is experimentally studied. The system ...

Abstract: The behavior of dilute polymer solutions in the inlet region of a round tube has been analyzed with a Rivlin-Ericksen approximation to describe the fluid properties. It is shown that for ...

Abstract: The heat transfer through an automated venetian blind window system is theoretically studied. The assumptions for the solution of the problem were: Heat transfer is unidimensional, heat exchanges ...

Abstract: Dimensional considerations on the torque coefficient of coaxial cylinders, inner one rotating and outer one at rest, result in the expression CM = f(T/Ri , Re) where Re is the Couette Reynolds ...

Abstract: Steady natural convection heat transfer has been studied in porous wall, solar collector systems. The boundary conditions were: two isothermal walls at different temperatures, two horizontal ...

Abstract: A thermochemical nuclear hydrogen producing process has been developed and evaluated from thermodynamics and engineering points of view. The cycle is based on sulfuric acid decomposition process ...

Abstract: The turbulent flow characteristics of non-Newtonian dilute polymer solutions around an enclosed rotating disk have been studied both theoretically and experimentally. In the theoretical analysis, ...

Abstract: Natural convection heat transfer has been studied in a sealed small PCB enclosure of three heated components which are mounted on a PCB plate within a large console cooled by vented airflow. ...
