The aim of the research presented here is to develop a new experimental device which would permit the study of multiscale and vertically-variable oceanographic flows using a system called the Hydraulic-Control Wave-maker (HCW). Both the inlet and outlet flume boundaries are composed of an adjustable set of vertical baffles. Each baffle is connected to an individual flow control system, such tha...

Sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. In recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. On the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...

The demand for liquid carriers, such as liquefied natural gas (LNG), has increased in recent years. One of the most common types LNG carriers is membrane type, which often built by a shipyard with prismatic tank shape. This carrier commonly known its effective ways to mitigate sloshing using baffle. Therefore, this study was performed evaluate vertical and T-shape baffles. conducted 25% 50% fil...

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...

For the last 8 years, the Brevard County Surface Water Improvement Program has used baffle boxes for stormwater sedimentation control at over 34 locations. As part of a Florida Department of Environmental Protection Demonstration Project for Indialantic Area Baffle Boxes, two baffle boxes were constructed in series on a 9.75 ha (24.1 ac) drainage basin in Sunset Park, near Indialantic. The firs...

Background: Heat exchanger is a device in many industrial applications and energy conversion systems. Various heat exchangers are designed for different industrial processes and applications. Shell and tube heat exchanger (STHE) has its own importance in the process industries. Methods: Experimental and numerical simulations are carried for a single shell and multiple pass heat exchangers with ...

The sound field of finite dipole acoustic transducers in a steel tool was investigated and their horizontal by measuring their vertical radiation patterns in water at two different frequencies. Measurements were also made with the tool in scale models representative of sonic logging conditions in the field. A Lucite borehole model was used to represent a soft formation and an Austin Chalk boreh...

Sloshing flows in a two-dimensional rigid rectangular tank under specified excitations in the coupled horizontal and vertical modes are simulated by using a higher-order boundary element method BEM . The liquid sloshing is formulated as an initial-boundary-value problem based on the fully nonlinear potential flow theory. And a semi-mixed Eulerian-Lagrangian technique combined with the 4th-order...

This article presents heat transfer and fluid flow characteristics in a solar air heater (SAH) channel with multi V-type perforated baffles. The flow passage has an aspect ratio of 10. The relative baffle height, relative pitch, relative baffle hole position, flow attack angle, and baffle open area ratio are 0.6, 8.0, 0.42, 60 ̋, and 12%, respectively. The Reynolds numbers considered in the stud...
