Abstract:

This master thesis project was performed in collaboration with Scania CV AB, Engine Materials group. The purpose with the project was to investigate different ceramic TBC (Thermal Barrier Coating) thermal insulation properties inside the combustion chamber. Experimental testing was performed with a Single-Cylinder engine with TBC deposited on selected components. A dummy-valve was developed and manufactured specifically for this test in order to enable a water cooling system and to ease the testing procedure. The dummy-valve consists of a headlock, socket, valve poppet and valve shaft. Additio

Abstract:

The design of aeronautical engines is subject to many constraints that cover performance gain as well as increasingly sensitive environmental issues. These often contradicting objectives are currently being answered through an increase in the local and global temperature in the hot stages of the engine. As a result, the solid parts encounter very high temperature levels and gradients that are critical for the engine lifespan. Combustion chamber walls in particular are subject to large thermal constraints. It is thus essential for designers to characterize accurately the local thermal state of

Abstract:

Modern diesel engines are being continuously developed in order to improve their specific output thus reducing the fuel consumption. This is in response to both increasingly stringent regulations and to the demands of the customer evolving. With this in mind a more detailed understanding of some of the fundamental processes within the engine are required. A prime example of one of these processes is heat transfer. In the region of 17-35% of fuel energy will pass to the coolant, therefore the rate of heat transfer has a considerable effect on the design and function of the engine. This thesis d

<p> In-cylinder heat transfer is one of the most critical physical behaviors which has a direct influence on engine out emission and thermal efficiency for IC engine.

Controlling unsteady combustion induced gas flow fluctuations and the resultant motor vibrations is a very significant step in rocket motor design.

Abstract:

Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. Generally, an engine simulation based on one-dimensional gas dynamics uses turbocharger performance maps which are measured without quantifying and qualifying the heat transfer, regardless of the fact that they are measured on the hot-flow or cold-flow gas-stand. Since heat transfer situations vary for on-engine turbochargers, the maps have to be shifted and corrected in the 1-D engine simulation, which mass and efficiency

У теоретичній частині роботи вперше розглядається задача дослідження ядерного магнітного резонансу для впливу на електрофізичні показники вуглеводневих палив, що характеризують процес горіння палива в камері згоряння та експлуатаційні властивості теплових двигунів. Експериментальна частина роботи присвячена досл

Abstract:

The recent resurgence in hypersonics is centered around the development of SCRAMJET engine technology to power future hypersonic vehicles. Successful flight trials by Australian and American scientists have created interest in the scramjet engine research across the globe. To develop scramjet engine, it is important to study heat transfer effects on the engine performance and aerodynamic forces acting on the body. Hence, the main aim of present investigation is the design of scramjet engine configuration and measurement of aerodynamic forces acting on the model and heat transfer rates along

Abstract:

碩士<br>國立臺灣科技大學<br>機械工程系<br>105<br>The in-cylinder flows in the axial planes of a motored two-vavle, single-cylinder, four-stroke engine during the intake and compression strokes at an engine speed of 6000 RPM and throttle opening of 100% were diagnosed by using computational methods. Moderate and intense tumble motions were generated by changing the combustion chamber geometric design. The computations were carried out by the computational fluid dynamics (CFD) software CONVERGE. The ensemble averaged conservation equations for mass, momentum, and energy in transient state conditions with the k
