Investigation of the effects of gasoline and CNG fuels on a dual sequential ignition engine at low and high load conditions
(Elsevier Sci Ltd, 2018)
In this study, a dual sequential spark ignition engine is separately tested either with gasoline or CNG at low and high loads. In addition, numerical engine analyses are performed by constructing a 1-D engine model in ...
Labyrinth Seal Leakage Degradation Due to Various Types of Wear
(Asme, 2017)
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 ...
Flow Resistance Coefficients of Porous Brush Seal as a Function of Pressure Load
(Asme, 2018)

Computational Fluid Dynamics Investigation of Labyrinth Seal Leakage Performance Depending on Mushroom-Shaped Tooth Wear
(Asme, 2016)
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 ...
Computational Fluid Dynamics Investigation of Brush Seal Leakage Performance Depending on Geometric Dimensions and Operating Conditions
(Asme, 2016)
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, ...
Effects of equivalence ratio and CNG addition on engine performance and emissions in a dual sequential ignition engine
(SAGE PUBLICATIONS LTD, 2020)
Compared to widening usage of CNG in commercial gasoline engines, insufficient but increasing number of studies have appeared in the open literature during last decades, while engine characteristics need to be quantified ...
A Study of Cloth Seal Leakage Performance Based on Geometry and Pressure Load
(MDPI, 2020)
Metal cloth seals have been used increasingly in gas turbines due to their flexibility and superior leakage performance. Leakage performance of a metal cloth seal depends on operating conditions, slot and geometric dimensions. ...
Experimental investigation of effects of single and mixed alternative fuels (gasoline, CNG, LPG, acetone, naphthalene, and boron derivatives) on a commercial i-DSI engine
(TAYLOR & FRANCIS INC, 2020)
A commercial i-DSI (Intelligent-Dual Sequential Ignition) engine is tested to investigate performance and emissions for single fuels and alternative fuels mixed into gasoline. The novelty of the study is the first time ...
Evaluation of flow behavior for clearance brush seals
(Asme-Amer Soc Mechanical Eng, 2008)
