RISAn Experimental Study of Mist/Air Film Cooling on a Flat Plate With Application to Gas Turbine Airfoils—Part I: Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film cooling is a cooling technique widely used in highperformance gas turbines to protect the turbine airfoils from being damaged by hot flue gases. Motivated by the need to further improve film cooling in terms of both ...
An Experimental Study of Mist/Air Film Cooling On a Flat Plate With Application to Gas Turbine Airfoils—Part II: Two Phase Flow Measurements and Droplet Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A phase Doppler particle analyzer (PDPA) system is employed to measure the twophase mist flow behavior including flow velocity field, droplet size distribution, droplet dynamics, and turbulence characteristics. Based on ...
Simulation of Char Dust Combustion Inside a Pyroscrubber Downstream of a Petroleum Coke Calcining Kiln
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pyroscrubber is a furnace used in the petroleum coke calcining industry to recover energy from the carbonaceous contents, including char dust and hydrocarbon volatiles of the exhaust gas from ...
On the Ideal Grid Resolution for Two Dimensional Eulerian Modeling of Gas–Liquid Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study was performed to investigate the interesting observation that when using an Eulerian–Eulerian model to simulate a bubble column flow in two dimensions, accuracy did not always increase with increasing grid ...
Geometric Closure Control of the Main Channel Girder of Jiaxing-Shaoxing Bridge
Publisher: American Society of Civil Engineers
Abstract: The main channel girder of Jiaxing-Shaoxing Bridge is the first six-tower, separate-deck, space four-cable-plane cable-stayed bridge in the world. The main bridge has seven closures, and the closure scheme is complex. ...
Validation of a Two-Phase CFD Air/Mist Film Cooling Model With Experimental Details—Part I: Development of an Experimental Test Facility
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film cooling is a cooling technique widely used in high-performance gas turbines to protect the turbine airfoils from being damaged by hot flue gases. Motivated by the need to further improve the turbine hot section cooling ...
Thermal Analysis and Simulation of Auxiliary Bearings and Its Application in the High Temperature Reactor 10
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The auxiliary bearing is applied to provide mechanical uphold for the rotational dropping rotor when contact event happens due to the active magnetic bearing (AMB) failure emergencies. During the rotor drop process, the ...
Dynamic Analysis for the Rotor Drop Process and Its Application to a Vertically Levitated Rotor/Active Magnetic Bearing System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Active magnetic bearings (AMBs) have been utilized widely to support high-speed rotors. However, in the case of AMB failure, emergencies, or overload conditions, the auxiliary bearing is chosen as the backup protector to ...
Hydrodynamics Modeling of a Piezoelectric Micro-Robotic Fish With Double Caudal Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical hydrodynamics model for a piezoelectric micro-robotic fish with double caudal fins is presented in this paper. The relation between displacement of the piezoelectric actuator and oscillating angle of the ...
