Brush seal temperature distribution analysis
(Asme, 2006)
Brush seals are designed to survive transient rotor rubs. Inherent brush seal flexibility reduces frictional heat generation. However high surface speeds combined with thin rotor sections may result in local hot spots. ...
Leakage Degradation of Straight Labyrinth Seal Due to Wear of Round Tooth Tip and Acute Trapezoidal Rub-Groove (conferenceObject)
(Amer Soc Mechanical Engineers, 2016)
In this paper, labyrinth seal leakage is numerically quantified for an acute trapezoidal rub-groove accompanied with a rounded tooth, as a function of rub-groove sizes and tooth-groove axial positions. Analyses parameters ...
Labyrinth Seal Leakage Degradation Due to Various Types of Wear (conferenceObject)
(Amer Soc Mechanical Engineers, 2016)
This paper systematically presents a complete leakage comparison for various types of wear experienced by labyrinth seals. Labyrinth seals used in turbine engines are designed to work at a clearance during steady-state ...
Leakage Degradation of Straight Labyrinth Seal Due to Wear of Round Tooth Tip and Acute Trapezoidal Rub-Groove
(Asme, 2017)
In this paper, labyrinth seal leakage is numerically quantified for an acute trapezoidal rubgroove accompanied with a rounded tooth, as a function of rub-groove sizes and toothgroove axial positions. Analyses parameters ...
Design And Cfd Analysis Of A 150 Kw 8-Stage Orc-Rot (Organic Rankine Cycle - Radial Outflow Turbine) And Performance Degradation Due To Blade Tip Clearance Of Labyrinth Seal
(Amer Soc Mechanical Engineers, 2018)
In this study, blade tip leakages were calculated for a Radial Outflow Turbine (ROT) designed for an Organic Rankine Cycle (ORC) at a 150kW power output. Since the turbine blade sizes are relatively very small for low-capacity ...
1-D Modelling Comparative Study to Evaluate Performance and Emissions of a Spark Ignition Engine Fuelled with Gasoline and LNG
(E D P Sciences, 2016)
In this study, a spark-ignition engine fuelled with gasoline and LNG was modelled in 1-D at wide open throttle by using Ricardo-Wave software. Different engine speeds ranging from 1500rpm to 4500rpm with an increment of ...
Robotics and Servo Press Control Applications: Experimental Implementations
(Ieee, 2016)
Three case studies are performed in robotics and industrial servo press mechanism by using system's nonlinear dynamics. Robotic systems and servo crank press are currently available in Mechanical Engineering Department's ...
Brush seal temperature distribution analysis (conferenceObject)
(Amer Soc Mechanical Engineers, 2005)
Brush seals are designed to survive transient rotor rubs. Inherent brush seal flexibility reduces frictional heat generation. However, high surface speeds combined with thin rotor sections may result in local hot spots. ...
CFD Investigation of Brush Seal Leakage Performance Depending on Geometric Dimensions and Operating Conditions
(Amer Soc Mechanical Engineers, 2015)
Brush seals require custom design and tailoring due to their behavior driven by flow dynamic, which has many interacting design parameters, as well as their location in challenging regions of turbomachinery. Therefore, ...
CFD Investigation of Labyrinth Seal Leakage Performance Depending on Mushroom Shaped Tooth Wear
(Amer Soc Mechanical Engineers, 2015)
Conventional labyrinth seal applications in turbomachinery encounter a permanent teeth tip damage and wear during transitional operations. This is the dominant issue that causes unpredictable seal leakage performance ...
