Elucidating cold-air-pooling processes forms part of the longstanding problem of 5 parametrizing the effects of complex terrain in larger-scale numerical models. The Weather 6 Research and Forecasting model has been set-up and run at high resolution over an ideal7 ized alpine-valley domain with a width of order 10 km, to investigate the four-dimensional 8 variation of key cold-air-pooling forci...

Using numerical techniques we studied the global stability of cooling flows in giant elliptical galaxies. As an initial equilibrium state we choose the hydrostatic gas recycling model (Kritsuk 1996). Non-equilibrium radiative cooling, stellar mass loss, heating by type Ia supernovae, distributed mass deposition, and thermal conductivity are included. Although the recycling model reproduces the ...

Disappointing results of pharmacological therapy in many patients with atrial fibrillation (AF) have motivated efforts to develop device therapy for this complex electrical disorder. Such devices have focused on mechanisms including ablation of tissue harboring triggers or substrates, mechanical devitalization of the left atrial appendage to provide antiarrhythmic as well as antithrombotic effe...

Several generalized state-space models arising from a semi-discretization of a controlled heat transfer process for optimal cooling of steel profiles are presented. The model orders differ due to different levels of refinement applied to the computational mesh. 1 The model equations We consider the problem of optimal cooling of steel profiles. This problem arises in a rolling mill when differen...

In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...

T he cooling performance of oil is critical to the functionality and durability of vehicle drive units, such as transmissions and differentials. Traditionally, automotive R&D teams evaluate cooling performance by building prototypes, installing them in a vehicle, and conducting tests in wind tunnels. The use of free-surface multiphase flow modeling with high-performance computing (HPC) has made...

background heat is a harmful factor in workplaces that causes physiologic and cognitive changes in workers. objectives the purpose of this study was to investigate the effect of cooling vest on heat strain and reaction time while wearing chemical-biological-nuclear protective clothes. methods twelve male students with mean age of 25 ± 2 and body mass index (bmi) of 23 ± 1.5 were recruited in th...

A 3D computational electromagnetic-thermal coupled analysis was performed to analyze the effects of auxiliary cooling fans, called air-gap fans, on winding cooling in a large-capacity, high-speed induction motor. A novel non-uniform iron loss distribution mapping method considering time and rotation period was introduced to provide more accurate thermal modeling. Winding cooling performance in ...
