Helical Baffle Thermohydraulic Performance Versus Segmental Baffle One

Effect of baffle oientation on shell tube heat exchanger performance

In this paper, fluid flow and heat transfer in the laboratory (small size) shell tube heat exchanger are analysed by computational fluid dynamic software. In this type of shell tube heat exchanger baffles with different angles of rotation: 00 (horizontal segmental baffle), 150 (from horizontal), 300, 450, 600, 750, 900 (vertical segmental baffle) is used. Effect of baffle orientation on shell t...

Baffle Material Characterization for Advanced LIGO by Cassandra

The transition to Advanced LIGO introduces new sensitivity requirements for the LIGO interferometers. When light scatters away from the main laser beam, then scatters off the beam tube and returns to the main beam, noise is introduced into the phase of the laser. The Auxiliary Optics Support subsystem uses baffles and beam dumps to control this scatter, but the baffle material and shape contrib...

Experiments and numerical modeling of baffle configuration effects on the performance of sedimentation tanks

Dynamic Emission Baffle Inspired by Horseshoe Bat Noseleaves

The evolution of bats is characterized by a combination of two key innovations-powered flight and biosonar-that are unique among mammals. Bats still outperform engineered systems in both capabilities by a large margin. Bat biosonar stands out for its ability to encode and extract sensory information using various mechanisms such as adaptive beamwidth control, dynamic sound emission and receptio...

Baffle Repair for Transposition of the Great Arteries

Forty-nine patients with transposition of the great arteries who underwent a Mustard atrial baffle repair between 1964 and 1971 were assessed late postoperatively. There have been five late deaths: two related to baffle obstruction, two from noncardiac causes, and one sudden and unexpected. Hemodynamic data were available in 42 patients and autopsy in four. Obstruction of the lower venous chann...
