The increase in energy demand, the scarcity of resources, as well adverse environmental impact burning fossil fuels make it necessary to diversify sources used. This also applies residential sector, which accounts for a significant proportion global consumption. Particular attention should be paid water heating, importance this process balance buildings is steadily increasing. One methods used ...

In this study, the liquid sloshing in a cylindrical tank considering soil–structure interaction and undergoing horizontal excitation is investigated analytically. Multiple rigid annular baffles are positioned on wall to mitigate sloshing. Firstly, combined with subdomain partition method for sloshing, complex domain partitioned into simple subdomains single condition boundary. Based continuity ...

As part of the Advanced Virgo upgrade for O5 observation run in 2026, a more powerful laser and larger end mirrors Fabry–Perot cavities will be installed. The new optical configuration increase beam waist cryogenic trapping area close to towers. This could require enlarging apertures vacuum pipe, now dictated by presence baffle, order avoid clipping noise due coupling with baffle vibrations, po...

Three patients developed late pulmonary vein obstruction (PVO) following Mustard's operation for transposition of the great arteries. In all three the absence of PVO had been documented by an earlier postoperative cardiac catheterization. At reoperation shrinkage and kinking of the dacron baffle was evident. After Mustard's operation, patients should be observed closely for symptoms and signs o...

Methods We performed a retrospective review of patients late after Fontan operation who underwent CMR measurement of APC flow at our institution from 2003 through 2009. APC flow was quantified as either aortic flow minus total caval flow or aortic flow minus sum of branch pulmonary artery flow, and was indexed to body surface area (BSA). Patients with a patent fenestration or baffle leak were e...

The benefits of a baffle fenestration in essentially high-risk Fontan patients have been demonstrated. Described here is the use of a new fenestration between the left atrial appendage and the left superior vena cava after Kawashima operation in a patient with a double-outlet right ventricle with hypoplastic left ventricle, left atrial isomerism, bilateral superior vena cavae with no bridging v...

Fluids have played and still play a vital role in attaining an optimized output from industrial processes. However, due to technological advancement, fluids with high hydrothermal characteristics are required. In order overcome these challenges, researchers developed dispersed nanoparticles, which recognized as nanofluids. Various types of nanoparticles can be added base produce thermally enhan...

Superconducting niobium cavities are important components of linear accelerators. Buffered chemical polishing (bcp) on the inner surface of the cavity is a standard procedure to improve its performance. The quality of bcp, however, has not been optimized well in terms of the uniformity of surface smoothness. A finite element computational fluid dynamics (cfd) model was developed to simulate the...

In this paper, a solar air collector duct equipped with baffles on back plate was numerically investigated. The Reynolds number (Re) varied from 5000 to 20,000, the angle baffle (a) 30° 120°, spacing ratio (Pr) 2 8, and blockage (Br) 0.375 0.75 examine their effects Nusselt (Nu), friction factor (f), thermohydraulic performance parameter (η). 2D numerical simulation used standard k-ε turbulence...
