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...

A young woman with congenital heart disease including dextrocardia presented to us following an out-of-hospital ventricular fibrillation (VF) arrest. She had a dual-chamber pacemaker inserted already for bradycardia. Therewere concerns over the risk of baffle occlusion due to multiple transvenous wires. She received an entirely right-sided subcutaneous implantable cardioverter-defibrillator wit...

A numerical study was performed for a T-shaped microchannel to enhance mixing performance through a baffle configuration. The mixing performance was analyzed in terms of the DOM (degree of mixing) and the pressure load between the two inlets and outlet. Four different baffle configurations were designed and simulated to determine how they affect the mixing performance of a T-shaped microchannel...

Building acoustic beamformers is a problem whose solution is hindered by the wide-band nature of audible sound. In order to achieve a consistent directional response over a wide range of frequencies, a conventional acoustic beamformer needs a high number of discrete loudspeakers and be large enough to achieve a desired low-frequency performance. The acoustic beamformer design described in this ...

The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument, a 10-channel infrared (1.27 16.9 μm) radiometer, was launched on the TIMED (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) satellite in December 2001 from Vandenburg Air Force Base. SABER is being used to measure earthlimb emissions and to characterize infrared radiation, allowing calculation o...

Twelve patients with dextro-transposition of the great vessels (age eight months to four years) were studied by echocardiography following Mustard's procedure. Nine of them had also been studied preoperatively. Postoperatively all patients demonstrated structural echoes in the atrial cavity behind the pulmonary root. In ten, the motion pattern generally resembled that of a stenotic atrioventric...

Oscillating buoy device, also known as point absorber, is an important wave energy converter (WEC) for development and utilization. The previous work primarily focused on the optimization of mechanical design, buoy’s array configuration site selection with larger density in order to improve generation performance. In this work, enlightened by potential availability Bragg reflection induced mult...

In this contribution, we reworked the Bell-Delaware technique for a HB-STHX to systematically study its thermohydraulic performance behavior in shell side. The helical baffles are continuous quadrant sectors with five inclination angles 25°, 30°, 35°, 40° and 45° exanimated six different values of Reynolds number from up 40 . We have observed an increase global heat transfer rate while decrease...
