Impacts of Using Al2O3 Nano Particle to Compressor Oil on Performance of Automobile Air Conditioning System
Nov 6, 2024Journal Frontiers in Heat and Mass Transfer
DOI https://doi.org/10.32604/fhmt.2024.052671
Issue 3
Volume 22
This work involves an experimental study on the performance of automobile air-conditioning systems by adding Al2O3 nanoparticles to oil compressors to investigate their impacts on the enhancement of the speed cooling of refrigeration systems and to compare it with the system operated using only oil. The Al2O3 nanoparticles have been added to the oil compressor for different ranges of mass concentration (Ø =0.1%, Ø=0.15% and Ø=0.2%). The stability of Al2O3 nanoparticles has been tested by direct observation for different time periods. The results indicated that the air conditioning system that operated by using Al2O3-oil was better than the system that operated with pure oil. For Ø = 0.2%, the results indicated that the cooling speed and the efficiency of the system operated with Al2O3-oil are increased by 13% and 18%, respectively, as compared to the pure oil system. This study shows that the thermos-physical properties of refrigerant oil are enhanced by 15% when Ø is increased.
ENERGY CONVERSION OF V-CORRUGATED ABSORBER PLATE SOLAR AIR HEATER WITH PHASE CHANGE MATERIAL
Sep 6, 2023Journal International Journal on “Technical and Physical Problems of Engineering”
Issue 56
Volume 15
The solar collector is one of the significant passive solar energy usages. Phase change material (PCM) has been used in experiments to test the efficiency of the standard solar air heater's V-corrugated absorber portion. Paraffin wax phase transition material has been utilized with solar air heaters as a storage method of thermal energy. The highest convection heat transfer for heat discharge throughout the night and the absence of solar radiation was present as a latent heat. It was conducting with keeping constant of all dimensions for the two collectors under 0.013 kg/s flow rate and Iraq climatic conditions (36.348°N, 43.1577°E). The results indicated that the performance of V-corrugated absorber plate solar collector is 63.2% as compared to the classical heater which is 29.2% during April 2021. It was illustrated that the modified solar collector outlet temperature is increased as compared the classical collector. The maximum difference of air temperature inlet and outlet collector were 17.6°C and 26.5°C for the V-corrugated absorber plate solar heater respectively. The V-corrugated absorber plate solar collector was shown to increase thermal efficiency and improve exit air temperature while lowering heat loss.
The Effect of Vibration on the heat transfer from a vertical plate: A Review

The influence of free or forced convection heat transfer becomes an essential element in laminar and turbulent flows. There have been numerical and experimental methods introduced in studying the convection in (tubes or plates) with different angular positions for conditions such as temperature-dependent fluid density, constant wall temperature, and parabolic profile axial velocity at (tubes or plates) entrance. In all cases, heating and cooling has been considered. The current research is an extension to free or forced convection, where it unravels the effect of Vibration on heat transfer performance of free or forced convection. This section presents the literature review to observe possible gaps in the literature concerning the topic under discussion, which informs further research.
