Flow Control Around a Cylinder With a Perforated Cylinder

Journal of Fluids Engineering, 2023
In this work, periodic vortex shedding at both sides of a circular cylinder is aimed to be suppressed using a concentrically located perforated cylinder under laminar flow conditions at Re=200.

Failure prediction of low-carbon steel pressure vessel and cylinder models

International Journal of Pressure Vessels and Piping, 1987
Abstract The failure loads predicted by failure assessment methods (namely the net-section stress criterion; the EPRI engineering approach for elastic-plastic analysis; the CEGB failure assessment route; the modified R6 curve by Milne for strain hardening; and the failure assessment curve based on J estimation by Ainsworth) have been compared with ...

High sensitivity optical fiber pressure sensor based on thin-walled oval cylinder

, 2020
In this study, an optical fiber pressure sensor based on a thin-walled oval cylinder is proposed. To sense the degree of deformation, a pair of fiber Bragg gratings (FBGs) are fixed on the outer wall of the oval cylinder.

High-Accuracy Low-Cost Cylinder Pressure Sensor for Advanced Engine Controls

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">A high-accuracy and low-cost cylinder pressure sensor reported in this paper compensates for all major temperature errors encountered in internal combustion engines. The auto-referencing technique maintains sensor calibration compensating for temperature effects on the sensor signal conditioner over the range of ...

Preparation of Microcellular Injection-Molded Foams Using Different Types of Low-Pressure Gases via a New Foam Injection Molding Technology

Industrial & Engineering Chemistry Research, 2019
A new foam injection molding (FIM) machine was recently developed with a physical blowing agent directly delivered from its gas cylinder, while the supercritical fluid pumping unit is a must in the conventional FIM process.

Resolving vortex-induced pressure fluctuations on a cylinder in rotor wake using fast-responding pressure-sensitive paint

The Physics of Fluids, 2019
The interaction between rotor wake and a cylinder has been studied experimentally in the current work. The cylinder was placed in close proximity to the rotor plane, and the pressure fluctuations induced by the rotor wake on the cylinder surface were ...

Prospects of using two-tier low-pressure cylinders in steam-turbine power units

Thermal Engineering, 2009
Possible ways for increasing the throughput capacity of the low-pressure cylinders of the condensing steam turbines are discussed. It is shown that the use of two-tier low-pressure cylinders allows the flowrate of steam through them to be increased by 65–70% without the need of increasing the length of last-stage blades.
