Abstract:

This paper presents a numerical investigation on the combined influences of film cooling and thermal barrier coatings (TBCs) on the cooling performances of a NASA C3X guide vane. The results show that: (1) film cooling on the pressure side is more effective than suction side, especially on the trailing edge where multiple cooling and thermal protection techniques include internal cooling and TBCs are necessary. (2) TBCs show positive and negative roles in improving cooling performance at the same time for the coated vane with or without film cooling. Without film cooling, TBCs show negative ro

Abstract:

Automation of cooling system in machine tools is an effective method for achieving higher productivity and increased tool life. A cooling system is designed to control the operating temperature on the cutting tool tip by circulating coolant through a reservoir built on the top of the machine tool. This arrangement maintains the coolant flow rate as per variation of cutting tool tip temperature sensed by LM-35 temperature sensor which is located 1 cm away (calibrated distance) from the cutting tool tip and whose output voltage is linearly proportional to the temperature. Coolant flow rate is va

Abstract:

The need for effective cooling methods has become very critical because of the miniaturization and increasing heat flux density in power electronics equipment. The power electronics systems must have good thermal management engineering for efficiency and safe operation. Due to increasing heat loads, liquid cooling options are more preferred than the air cooling solutions. In this study, thermal performance of a liquid cooling plate is investigated by using computational fluid dynamics (CFD) tools.

Abstract:

Simulations of the thermal and dynamical evolution of primordial gas typically focus on the role played by H 2 cooling. H 2 is the dominant coolant in low-density primordial gas and it is usually assumed that it remains dominant at high densities. However, H 2 is not an effective coolant at high densities, owing to the low critical density at which it reaches local thermodynamic equilibrium and to the large opacities that develop in its emission lines. It is therefore important to quantify the contribution made to the cooling rate by emission from the other molecules and ions present in the ga

The excessive use of fossil fuels could bring about a global environmental crisis.

Hydrogen liquefaction is an efficient technology for the transportation and storage of hydrogen, and the liquid hydrogen produced is also a direct feedstock for many important fields.

The high pressure turbine nozzle guide vane of a modern aeroengine experiences large heat loads and thus requires both highly effective internal and external cooling. This can be accomplished with double-wall effusion cooling, which combines impingement, pin-fin and effusion cooling. The combination of three cooling mechanisms causes high pressure losses, increasing potential for the migration of coolant towards low pressure regions, subsequently starving effusion holes on the leading edge of coolant supply.

Abstract:

In this study, the potential usage of hybrid nanofluids for brushless direct current (BLDC) motor cooling was compared. Due to their efficiency, durability, and small size, brushless direct current (BLDC) motors are a type of electric motor that are frequently employed in electric vehicles (EVs). In order to maintain appropriate operating temperatures and ensure long-term durability, cooling systems must be taken into account throughout the design of brushless direct current (BLDC) motors. Because excessive heat can shorten a motor's lifespan and affect its performance, effective cooling is cr

Abstract:

Super alloys is the ideal material for high temperature components although it has a great difficulty to cut, especially drilling. Minimum Quantity Lubrication (MQL) has a good advantage of green, lubricating and cooling effect. Comparison experiments of MQL cooling drilling and pouring cooling drilling were done with coolant holes in drill. The results show that: the maximum measure temperature is less than 100°C and the amount of wear is very small. Internal Minimum Quantity Lubrication drilling is an effective process to solve problems of high temperature and wear fast for super alloys dril

Abstract:

Object The use of focal brain cooling to eliminate epileptic discharges (EDs) has attracted increasing attention in the scientific community. In this study, the inhibitory effect of selective hippocampal cooling on experimental hippocampal seizures was investigated using a newly devised cooling system with a thermoelectric (Peltier) chip. Methods A copper needle coated with silicone and attached to the Peltier chip was used for the cooling device. The experiments were performed first in a phantom model with thermography and second in adult male Sprague–Dawley rats in a state of halothane anest

Abstract:

Inorganic multilayer films for radiative cooling have garnered significant attention due to their exceptional resistance to photothermal degradation. However, the design and fabrication of structurally simple and cost-effective inorganic multilayer films remain challenging due to limitations in material properties and the preparation process. This study develops a structurally simple inorganic multilayer film (Si3N4/SiO2/Al2O3/Si3N4/Al) for daytime radiative cooling. Instead of the conventional periodic alternation of high and low refractive indices (H-L…H-L), this work proposes a H-L-L-H symm

Abstract:

Abstract Nowadays, due to high external temperatures, the topic of cooling is very actual. However, cooling buildings is energy intensive. Therefore, it is necessary to focus on more than one method of cooling. We can say that cooling can be provided in 2 ways. By building services and by architectural design. For existing buildings, we cannot change the shape and orientation of the building. But we can change the composition of structures. Green architecture is often mentioned in this area. Therefore, the aim of this research is to interconnect these two areas and determine the influence of v

Abstract In this work, a cooling mechanism is proposed that can achieve adaptive adjustment to match the spatial thermal load distribution. Segmented copper blocks are adopted to realize discrete adjustments of effective cooling length according to the footprint variations of specific wavelengths; Holes are applied on the cooling blocks to further control the local cooling efficiency achieving local thermal shape adjustment; The coolant flow rate is also switchable to increase system adjustability and fault tolerance.

The utilization of an actively cooled thermal protection system is widely recognized as an effective approach to decrease the temperature of components exposed to severe aerodynamic heating. In this study, two cooling schemes with different flow paths and structural configurations were proposed, and six cooling channel designs were developed by modifying the leading-edge details. A numerical analysis on the heat transfer and thermal–mechanical performance was conducted under actual flight conditions (30 km altitude, Mach 8).

Abstract:

The performance of lithium-ion batteries in electric vehicles is significantly affected by temperature. To ensure battery stability and extend its lifespan, an effective cooling system must be developed for heat dissipation. Therefore, researchers are focusing on liquid-cooled systems that use fluids with higher thermal conductivities compared with conventional air-cooling systems. However, studies regarding the flow shapes of crucial cooling plates in indirect liquid-cooling systems are scarce. In this study, the optimal flow shape of cooling plates with high cooling performance for dissipati
