1-D Modelling Comparative Study to Evaluate Performance and Emissions of a Spark Ignition Engine Fuelled with Gasoline and LNG
Yontar, Ahmet Alper; Dogu, Yahya (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 ... -
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
Dogu, Yahya; Gunaydin, Ibrahim; Kilicaslan, Zeynal; Ileri, Tacettin; Soganci, Sinan (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 ... -
Labyrinth Seal Leakage Degradation Due to Various Types of Wear (conferenceObject)
Dogu, Yahya; Sertcakan, Mustafa C.; Gezer, Koray; Kocagul, Mustafa; Arican, Ercan; Ozmusul, Murat S. (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
Dogu, Yahya; Sertcakan, Mustafa C.; Gezer, Koray; Kocagul, Mustafa; Arican, Ercan; Ozmusul, Murat S. (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 ... -
