Flashing light effect on microalgae could significantly improve the light efficiency and biomass productivity of microalgae. In this paper, the baffles were introduced into the traditional flat plate photobioreactor so as to enhance the flashing light effect of microalgae. Making Chlorella sp. as the model microalgae, the effect of light intensity and inlet velocity on the biomass concentration...

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...

In the current study, this way was adopted numerically in order to optimize performance of a HEC through use extended solid sections form 'W' (W-baffles: WBs). All limit conditions channel have been defined, with all thermo-physical properties HTF (heat transfer fluid) used. The FVM (Finite-Volume-Method) has some necessary numerical schemes give solution, which allows us visualize dynamically ...

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...

The study shows an experimental investigation for a solar air collector with single pass by adding rectangular baffles different positions inside the channel. aim of this is to improve thermal efficiency collector, and that through testing four cases (mode 1, 2, 3, 4). was done under operating conditions changing mass flow rates baffles. results show effectiveness in improving also proved affec...

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...

In vertical Bridgman (VB) systems, the shape of S-L interface greatly influences yield and perfection single crystal, because continuous contact with crucible. The melt flows are difficult to modify control. Baffles flow-directing or obstructing devices. VB melts, baffles disk shaped, positioned horizontally above solid-liquid (S-L) interface. role baffle is to: i) minimize thermally-driven con...
