Abstract: Single-phase natural circulation thermosiphon loops have been attracting increased interest as they represent the prototype of passive safety systems. However, the stability properties of thermosiphon loops, which can ...

Abstract: In this study, we examine in detail the effect of spatially dependent viscosity on wall-bounded flow. For this purpose, direct numerical simulations (DNS) are performed considering a channel flow with a viscosity change ...

Abstract: To fully implement seismic performance-based design for geotechnical structures, it is necessary to be able to correctly identify relevant earthquake records for the site in question in conjunction with advanced constitutive ...

Abstract: A numerical study of natural convection induced in a horizontal, enclosed air layer due to a discrete, constant heat flux source at the bottom surface is carried out in this paper. The nature ...

Abstract: Space robots require compact joint drive systems (JDSs), typically comprising of actuator, transmission, joint elements that can deliver high torques through stiff mechanical ports. Today's conventional space drive systems ...

Abstract: A mathematical model is presented to analyze the performance of a countercurrent solar desalination system. Besides, the heat transfer equations, the mass transfer is also considered to improve the model precision. A new ...

Abstract: Now, there is no doubt that the problem of energy is extremely difficult and the discussions that are going on in our Congress reflect the fact. It's not simply as Dr. Belding says that Washington works in peculiar ways. ...

Abstract: Carnot analyzed an engine operating between two reservoirs. Through a peculiar mode of reasoning, he found the correct optimum shaft work performed during a cyclic change of state of the engine. Clausius justified Carnot's ...

Abstract: In structural health monitoring, the presence of damage is detected and localized by outlining the differences between the initial state and current behavior of a given structure. The problem is often formulated as an ...
