Background. The "fenestrated Fontan" (surgical baffle fenestration followed by transcatheter test occlusion and permanent closure after postoperative recovery) was adopted in an effort to reduce perioperative mortality and morbidity. This study assesses the effect of baffle fenestration on outcome. Methods and Results. Patients having a modified Fontan operation with a cavocaval baffle and cavo...

Convective heat transfer and entropy generation in a 3D closed cavity, equipped with adiabatic-driven baffle and filled with CNT (carbon nanotube)-water nanofluid, are numerically investigated for a range of Rayleigh numbers from 103 to 105. This research is conducted for three configurations; fixed baffle (V = 0), rotating baffle clockwise (V+) and rotating baffle counterclockwise (V−) and a r...

Sloshing refers to a certain kind of fluid movement that changes as it progresses. It possesses properties are both nonlinear and exceedingly unpredictable, these affect the tank wall. This effect may lead structural wear, which in turn can cause fail. Benzene gasoil liquids used test sloshing liquid accompanying pressure on wall caused by baffles partially full tanks. To attain this, modeling ...

Clinicians have a difficult choice between the arterial switch (Jatene et al.) and the atrial baffle operation (Mustard or Senning) for transposition of the great arteries. The surgical decision is essentially a determination of whether the long-term course after the arterial switch procedure (thought to be more favorable than after the atrial baffle procedure) plus elimination of presurgical a...

To the Editor Mustard operation, a surgical treatment for transposition of great arteries, can be complicated by postprocedural atrial or caval baffle leaks, which lead to about 60% of late reoperations. Transcatheter procedures for baffle leakage closure have been anecdotally reported and shown to be both well tolerated and effective; however, no data have been reported to date about the short...

The performance of ethanol distillation is determined by the type reboiler used in column. This study aims to determine effect differences diameter and height internal tubes, as well feed content on distillate concentration yield. research was conducted a batch process using rectified device with an vertical tubular baffle different diameters tube height, namely 1.5, 1, 0.5 inches diameter, 8, ...

A new virtual baffle methodology is implemented to solve contact/detach problem which is often encountered in fluid and structure interaction simulations while using dynamic grids technique. The algorithm is based on tetrahedral unstructured grid, and a zero thickness baffle face is generated between actually contacted two objects. In computation process, this baffle face is divided into two pa...

Exact solutions are derived for sound radiation from four kinds of infinitely-long strips: namely a rigid strip in a baffle of finite width, a resilient strip in free space, and a resilient or rigid strip in an infinite baffle. In one limit, the strip in a finite baffle becomes a rigid strip in free space and in the other, a line source in a finite baffle. Here "rigid" means that the surface ve...
