Water : Ethylene glycol properties alteration upon dispersion of Al2O3 and SiO2 nanoparticles

Proton exchange membrane fuel cell (PEMFC) seems to be a popular option as a green energy carrier due to its high efficiency and pollutant-free operation. However, the slight temperature difference between the working temperature and surroundings requires innovation in cooling strategy. Active thermal management strategy is limited due to the larger space requirement. Alternatively, utilizing nanofluids as coolant as the passive cooling strategy tends to be a viable quick fix. In this research, thermophysical properties of Al2O3:SiO2 hybrid nanofluids in the base fluid of water: Ethylene Glycol (EG) were discussed comprehensively concerning alterations made in thermal conductivity, dynamic viscosity, and electrical conductivity properties. There were four mixture ratios of 0.5% volume concentration of hybrid nanofluids considered ranging from 10:90, 30:70, 50:50, and 70:30 Al2O3:SiO2. Upon completion of the study, there is an improvement of 9.8% shown in 10:90 Al2O3:SiO2 hybrid nanofluids for thermal conductivity measured at 60°C in comparison to the base fluid. Meanwhile, 10:90 Al2O3:SiO2 hybrid nanofluids are also favorable with the lowest values of viscosity as compared to other mixture ratios resulting in lower parasitic loss. Electrical conductivity on the other hand also showed an increment in 10:90 Al2O3:SiO2 hybrid nanofluids as compared to base fluid and other mixture ratios

Heat transfer and pressure drop of water based hybrid Al2O3:SiO2 nanofluids in cooling plate of PEMFC

A Proton Electrolyte Membrane fuel cells (PEMFC) is considered to be a viable alternative to Internal Combustion Engines (ICEs) in automotive applications due to the key advantages in thermal management system. The main duty of thermal management system is to maintain the desirable temperature, with a uniform temperature distribution across the stack and its individual membranes. In this paper, the thermal enhancement for two types of PEMFC cooling plates were analysed and presented. The hybrid Al?O?:SiO? was used as coolant in distributor cooling plate. The study focuses on water based 0.5% volume concentration of single Al?O? , single SiO? nanofluids, hybrid Al?O?:SiO nanofluids with mixture ratio of 10:90 and 50:50. The effect of different ratios of nanofluids to heat transfer enhancement and fluid flow in Reynold number range of 400 to 2000 was observed. A 3D computational fluid dynamic (CFD) was developed based on distributor cooling plates using Ansys 16.0. Positive heat transfer enhancement was obtained where the 10:90 Al?O?:SiO? nanofluids has the highest heat transfer coefficient as compared to other nanofluids used. However, all nanofluids experienced higher pressure drop. Therefore, the advantage ratio was used to analyze the effect of both heat transfer enhancements and pressure drop demerits for nanofluids adoption. The results concluded that 10:90 Al?O?:SiO? hybrid nanofluid is the most feasible candidate followed by 50:50 Al?O?:SiO? Al?O? hybrid nanofluids up to fluid flow of Re1000. The positive results implied that hybrid Al?O?:SiO? nanofluids do improve the single nanofluids behaviour and has a better potential for future applications in PEMFC thermal management

People usually modified their vehicles with the purpose to make their vehicles to have an outstanding feature. As a result, the vehicle modifications grew to the extent that, it becomes extreme modification. There are certain modifications which are allowed by the authority. However, most of the modification done nowadays is not approve by the authority because they find it is unsuitable and dangerous. This unapproved modification can be regarded as illegal modifications by the authority. The Road Transport Department has identified high number of cases regarding the illegal modified cars and motorcycles in Peninsular Malaysia, which have been compounded. ITic purpose of this research is to study the enforcement conducted by the authority relevant to this matter. This project paper is based on an analysis of the legal statutes on illegal vehicle modifications which have been used as an authority.

Performance of hybrid Al2O3:SiO2 W:EG in PEM fuel cell distributor plate

Efficient thermal management is essential for the optimal performance and durability of the Proton Exchange Membrane Fuel Cell (PEMFC). However, the conventional passive cooling methods require a larger heat exchanger for better heat dissipation. Alternatively, nanofluids as a coolant have gained attention recently due to their enhanced heat transfer properties. This investigation aims to evaluate the thermal performance of hybrid nanofluids in a distributor type of PEMFC cooling plate. In this investigation, 0.5% volume concentration of mono Al2O3, mono SiO2 nanofluids, and hybrid Al2O3:SiO2 nanofluids with a mixture ratio of 10:90, 30:70, 50:50, and 70:30 in 60:40 W:EG were investigated. The cooling plate was modelled and a fixed heat flux of 6500 w/m2 was applied to replicate the actual working parameter of PEMFC. The study shows that the heat transfer coefficient was improved by 61% in 10:90 hybrid nanofluids of Al2O3:SiO2 in W:EG in comparison to the base fluid. Meanwhile, the accompanied pressure drops in 10:90 hybrid nanofluids of Al2O3:SiO2 in W:EG show a reduction up to 4.38 times lower as compared to single Al2O3 nanofluids at Re 1800. This is advantageous since it will reduce the parasitic loss related to the PEM fuel cell

Comparative study of indoor air contaminants in different stages of new building occupancy: work environment assessment

Indoor Air Quality (IAQ) is a part of Building Environment. Nowadays, the construction of new building took place over the world. Upon new building occupancy, a lot of indoors material was used without IAQ concern. This study has been conducted in a new constructed building of the National Institute of Occupational Safety and Health (NIOSH) Malaysia. The goal of the study is to monitor on the level of IAQ parameters including chemical and physical parameters within four consequent stages which are before furniture install, after furniture install and during one and three month occupancy. The indoor parameters have been measured consist of nine parameters including of Carbon Dioxide (CO2), Carbon Monoxide (CO), Total Volatile Organic Compounds (TVOC), Formaldehyde, Respirable Particulates (PM10), Ozone, Relative Humidity (RH), Temperature and Air Movement. The interaction between Malaysian and international standard was referred and utilized in collecting the data and analyzing of the findings. There was a significant correlation between the high values of RH, Formaldehyde and PM10 where (r 0.324, p <0.05), (r 0.344, p <0.05) and (r 0.319, p<0.05) with extension of phases of new building occupancy respectively. This study established significant different on Formaldehyde and Particulate Matter (PM10) concentration level as go along with the building occupancy. These finding indicated that furniture and fittings, indoor materials and human population has a potential sources of indoor air contaminants. It is recommended that the management should be aware to their indoor air status to protect the occupant from the risk of unwanted exposure especially during the early stage of building occupancy. Finally this research has fully supported the Malaysian need to formulate of future guideline on IAQ commissioning and maintenance of new building occupancy

Balancing act

Birds are always associated with symbols of freedom. This sentiment originates from the fact that birds are anatomically designed to fly and are able to manipulate space in 3 dimensions; sidewards, front to back, and up and down. Artistic impression of birds usually depicts flying movements and aerodynamic forms. Bird-themed arts often assert elements of flight patterns and graceful postures of birds perching
