Abstract:

The efficiency and longevity of modern automobile engines depend significantly on their thermal conditions, especially in desert-sandy areas where overheating is a frequent issue. The cooling system plays a crucial role in maintaining optimal thermal conditions, and its reliability is influenced by factors such as water pump efficiency, radiator cleanliness, and coolant quality. The accumulation of scale within the cooling system can severely impact heat dissipation, leading to engine wear and possible failure. Various chemical and mechanical methods are available for descaling and flushing th

Abstract:

Pollutants in exhaust gases and the high fuel consumption of internal combustion engines remain key issues in the automotive industry despite the emergence of electric vehicles. Engine overheating is a major cause of these problems. Traditionally, engine overheating was solved using electric pumps and cooling fans with electrically operated thermostats. This method can be applied using active cooling systems that are currently available on the market. However, the performance of this method is undermined by its delayed response time to activate the main valve of the thermostat and the dependen

Abstract:

The engine cooling system must be able to match up with the stable operating conditions so as to guarantee the engine performance. On the working cycle level, however, the dynamic thermo-state of engines has not been considered in the cooling strategy. Besides, the frequent over-cooling boiling inside the gallery changes the cooling capacity constantly. It is necessary to study the coupling effect caused by the interaction of cooling flow and in-cylinder combustion so as to provide details of the dynamic control of cooling systems. To this end, this study develops a coupled modeling scheme of

Abstract:

<em>Internal combustion engines are important machines that make human life easier. Internal combustion engines are developing day by day and higher power density engines are produced. Besides, strict standards of emission and fuel economy are forcing automotive manufacturers to produce environment-friendly engines. While manufacturers produce engines in accordance with these standards, they also do various studies in order not to reduce performance. One of the most important of these studies is the development of thermal management. Good cooling of internal combustion engine pistons, which ar

Abstract:

The majority of integrated energy systems (IES) for combined electricity, heat and refrigeration generation, or trigeneration, are based on gas engines. The fuel efficiency of gas engines are strictly influenced by intake air temperatures. Practically in all IES the absorption lithium-bromide chillers (ACh) are applied for conversing the heat removed from the engine into refrigeration in the form of chilled water. The peculiarity of trigeneration in food industries is the use of chilled water of about 12°C for technological needs instead of 7°C as typical for ACh. This leads to a considerable

Nanofluids have high thermal conductivity and can be used as vehicle engine coolant. In this article, the effects of Al2O3 nanoparticles to an engine coolant were experimentally investigated and the results were compared with the results of the original coolant including 50% ethylene glycol and 50% water mixture. The nanofluid was prepared by adding 0.5% Al2O3 nanoparticles by volume. The inlet temperature of the coolant was held constant at 95 Celsius. The tests were carried out at the air inlet temperatures between 23.4-28.6 ?C, the air velocity between 1.7-4.3 m/s, the cooling power between

Abstract:

The hydrocarbon liquid rocket engine working environment is harsh; the thrust chamber needs to withstand high temperatures and a high-pressure working environment, and the thrust chamber wall material is difficult to bear, so it is necessary to design the cooling structure to reduce the gas damage to the chamber wall. Liquid film cooling is a common cooling method for hydrocarbon rocket engines, and numerical simulation is an important method for studying liquid film cooling. Most of the liquid film cooling numerical simulation is for a fixed model. This paper proposes a liquid film cooling nu
