BACKGROUND Patients after atrial switch operation for transposition of the great arteries have limited exercise performance. Rigid atrial baffles may cause a relative preload reduction. Previous studies have had suboptimal control groups, which ideally should consist of patients with congenitally corrected transposition of the great arteries (ccTGA) without previous heart surgery, having a syst...

This paper investigates the dynamic coupling between fluid sloshing and the motion of the vessel containing the fluid, for the case when the vessel is partitioned using non-porous baffles. The vessel is modelled using Cooker’s sloshing configuration [M. J. Cooker, Wave Motion 20, 385–395 (1994)]. Cooker’s configuration is extended to include n − 1 non–porous baffles which divide the vessel into...

Vacuum technology is one of the established advanced technologies, of present age, in the field of research and industry. Having numerous applications, in the areas of human activities, one is concerned with a relatively large vacuum chamber where pressure distribution is, usually, not uniform during dynamic gas flow. To minimize the pressure non-uniformities in such chambers, baffles are gener...

Nowadays Diesel generator assemblies become an integral part of almost all the industries, large housing units and commercial shops as well. Keeping these units in a canopy with louvers will reduce the noise pollution and at the same time thermal behavior of this system becomes a challenging task. In this project a novel approach is taken using CFD, to understand the flow and thermal behavior o...

Background and Objectives: Pomegranate juice (PJ) contains large particles that stick to evaporator walls causing off flavors in the concentrate due to burning. Microfiltration is used to clarify PJ. Fouling is a limiting phenomenon that can prevent the industrialization of membrane clarification. Changes in the geometry of the membrane module such as using baffles are useful to decrease this p...

Submerged membrane bioreactors (MBRs) have been gaining in popularity in various types of wastewater treatment. One drawback of submerged MBRs is the difficulty in removing nitrogen because intensive aeration is usually carried out in the tank and the MBRs must therefore be operated under aerobic condition. In this paper, feasibility of a baffled MBR (BMBR), treating municipal wastewater partic...

The transient phenomena of incident shock waves during its passage through an orifice, a diverging nozzle, and a conical disk as baffles in a tube are numerically simulated. The influence of geometrical configurations of the baffles on shock attenuation is investigated. The results show that the conical disk was most effective configuration to weaken the strength of transmitted shock waves, sin...

The sloshing phenomenon is an important field of fluid dynamics in liquid storage tanks under earthquake excitation. When the frequency gets close to tank’s natural frequency, resulting resonance could lead instability and even damage structures, followed by catastrophic economic losses environmental damages. As passive control devices, baffles are a place for energy dissipation. This study use...
