Experimental Investigation on Light Weight Concrete by using Natural and Artificial Light Weight Aggregates

The changes of moisture content for the duration of drying are experimentally investigated in the current work. Particular emphasis is placed on the preliminary stage of drying of saturated concrete, when moisture contents are high, on account that the resistance of the fabric to numerous deterioration methods is reduced at high moisture content material levels, and experimental records for this stage of drying is lacking. The experimental investigation is carried out for concrete cylinders of one of a kind lengths with one give up uncovered to drying. In this way, moisture float is compelled to be unidirectional. The gravimetric approach is employed to gain moisture content distribution in the material at exceptional times of drying. The cylinders are made of lightweight concrete with varying water to cement ratios and moist curing times, and the influence of these variables upon the drying method is assessed. Higher preliminary water content and more speedy modifications of water content take place in light weight concrete with a greater w c ratio. An elevated moist curing period consequences in a minimize of drying fees during the drying process.

Numerical Analysis of Corrugated Type Heat Exchanger with Variation in Corrugation Angle

Heat transfer is one of the main concerns in industries. Corrugated type heat exchangers are one of the best options available for heat transfer in less space. Many researchers have worked for corrugated plate heat exchanger with configuration corrugation angle of 30°. In the present work, corrugated plate heat exchanger with 30° corrugation angle has been modeled and results have been compared with that of the base paper. Further the corrugation angle has been changed to 45°. The boundary conditions have been kept same as that for 30°. Heat transfer rate, Nusselt number, Reynolds number, Friction factor, Paclet number and their variation have been found out for the new geometry. Graphical plots, variation in temperature and water velocity streamlines have also been found out.

Heat Transfer Characteristics of a Plate Fin Heat Sink with Pin Fins of Various Profile using CFD

In recent decades, attempts have been made to create more advanced effective cooling technology for electronic and microelectronic devices, but heat dissipation is still a major challenge for increasing the cooling performance of heat sinks in a highly competitive electronics market. In the present analysis, the research is designing a new thermal design for plate fin heat sinks with hexagonal pin fin connected to the plate fins. A theoretical analysis focused on publicly usable computational fluid dynamics CFD codes has been performed to test the thermal efficiency of the proposed designs. Modelling done using ANSYS 14.5 and meshing has done using ICEM CFD software, simulations has done by using CFD FLUENT software. In specific, in terms of their thermal performance, hexagonal pin fin connected to the plate fins subject to flow have been contrasted. The plate fin heat sink was made of Aluminium and an electrical heaters provide a heat of 10W constantly to warm up a plate plate fin heat sink with hexagonal pin fin subject to flow of air at variable values i.e. 6.5, 9.5, and 2.5 m s .Based on the results, the analysis has shown that the plate fin heat sinks demonstrate superior thermal performance with hexagonal 3 pin fin subject to flow. The Nusselt number is approximately 1.32 times higher than the conventional plate fin heat sink without pin fin and 1.13 times higher than plate fin heat sink with elliptical 3 pin fin.

Performance and Emissions Characteristics of an Automotive Diesel Engine Fueled with Petroleum Based Fuel from Plastic Pyrolysis Oil and its Diesel Blends

An interesting alternative fuel for Diesel Engines in the form of liquid oil derived from waste plastics, to solve the problem arises from the depletion of fossil fuels and disposal problem of the very large amount of plastic wastes produced from households and industrials. This present paper describes the production and testing of Liquid fuel derived from waste plastics by the pyrolysis process at different proportions 10 , 20 , and 30 . The fuel produced is then tested in a fully instrumented diesel engine, without any engine modifications. The chemical properties such as GCMS, and FTIR results of the oil derived from waste plastics, compared with the diesel fuel, and found that it has similar properties to that of diesel fuel. The experimental investigation on the pyrolysis oil with diesel blends shows a notable increase in engine performance and a significant reduction in emission characteristics while compared with commercial diesel fuels. Thus, the results specify that modified plastic pyrolysis oil can be considered for an alternative fuel to diesel engines with better performance and reduce emission.

Heat Transfer Enhancement of Plate Fin Heat Sinks – A Review

Heat sinks have been commonly used for cool electrical, electronic and automotive parts in many industrial applications. They are effective in extracting heat at high temperatures from surfaces. The reliability of such systems depends on the temperature of their operation. Heat sinks are important components of most of these devices thermal management systems, such as diodes, thyristor, high power semiconductor devices such as integrated inverter circuits, audio amplifiers, microprocessors or microcontrollers. This paper highlights the use of heat sinks in electronic cooling applications, and discusses relevant literature to enhance the heat transfer efficiency of plate fin heat sinks by modifying the surface, interrupting the boundary layer and shifting the path.
