In cooperation with other institutions, GRS adapts and validates the CFX code developed by ANSYS for LWR containment applications. In a severe accident scenario in a LWR large amounts of steam and hydrogen are released into the containment at different locations. To simulate the main phenomena relevant for accident scenarios within LWR containments models, especially the ones provided to CFX by...

The mean curvature flow (MCF) arises material science and condensed matter physics and has been recently successfully applied to topological classification of surfaces and submanifolds. It is closely related to the Ricci and inverse mean curvature flow. The most interesting aspect of the mean curvature flow is formation of singularities, which is the main theme of these lectures. In dealing wit...

Condensers are often required in power generation systems to condense the exhaust steam generated at end of turbine. This paper will investigate enhanced condensation process spent a parallel flow type. The operating parameters temperature (Tcond), rate (Gin), cooling water (Tin), and (Lw) affect effect by changing gas–liquid arrangement tower. In this experiment, an orthogonal test was designe...

An atmospheric water harvester with a thermoelectric cooler (TEC) can extract vapour from air. This study tested prototype TEC and evaluated the condensation flow parameters affecting amount of produced using experimental numerical methods. experiment was performed under controlled conditions (a temperature 313 K relative humidity 85%) in climate chamber for 8 h actual weather Kuwait h. The hum...

A field theoretic description of monopole condensation in strongly coupled gauge theories is given by actions involving antisymmetric tensors Bμν of rank 2. We rederive the corresponding action for 4d compact QED, summing explicitly over all possible monopole configurations. Its gauge symmetries and Ward identities are discussed. Then we consider the Wilsonian RGs for Yang-Mills theories in the...

In this paper, a solid trap/thermal desorption-based odorant gas condensation system has been designed and implemented for measuring low concentration odorant gas. The technique was successfully applied to a medical electronic nose system. The developed system consists of a flow control unit, a temperature control unit and a sorbent tube. The theoretical analysis and experimental results indica...

SMC (structural maintenance of chromosomes) family members play essential roles in chromosome condensation, sister chromatid cohesion and DNA repair. It remains unclear how SMCs structure chromosomes and how their mechanochemical cycle regulates their interactions with DNA. Here we used single-molecule fluorescence microscopy to visualize how Bacillus subtilis SMC (BsSMC) interacts with flow-st...
