The W7-X plasma vessel (PV) is part of the cryostat wall and forms a vacuum thermal barrier between hot interior superconducting coils. thermally loaded from inside actively cooled by numerous cooling water pipes in order to control its temperature. However, due complex geometry large number different types ports, are distributed irregularly with varying distances them. So temperature distribut...

Thermal-hydraulic considerations in urban drainage networks are essential to utilise available heat capacities from waste- and stormwater. However, models either too detailed or coarse; fully coupled thermal-hydrodynamic modelling tools lacking. To predict efficiently water-energy dynamics across an entire network, we suggest the SWMM-HEAT model, which extends EPA-StormWater Management Model wi...

The importance of indoor mobile connectivity has increased during the last years, especially Covid-19 pandemic. In contrast, new energy-efficient buildings contain structures like low-emissive windows and multi-layered thermal insulations which all block radio signals effectively. To solve this problem with connectivity, we study passive antenna systems embedded in walls low-energy buildings. W...

Equipped with its Solver and-in and VBA, Microsoft Excel makes an ideal educational platform for design analyses of fluid-thermal systems. This paper illustrates this capability by considering a common type these systems; which is the double-pipe heat exchanger. While used optimisation analysis, VBA development user-defined function (UDF) that determines optimum standard-pipe size system.
