In the present study, the high viscosity of the jatropha curcas oil was decreased by preheating. The effect of fuel inlet temperature on performance of diesel engine is evaluated. A single cylinder, four stroke, constant speed, air cooled, direct injection diesel engine developing a power output of 3.7 kW at 1500 rev/min typically used in agricultural sector was tested using neat jatropha oil a...
This paper describes our experiences with Virtual Reality visualisation of CFD results in an immersive environment. The data for visualisation were simulation results of airflow and temperature distribution in livestock buildings. Four different configurations of ventilation system were studied. Low momentum air supply was studied with air supply near the floor and through the ceiling respectiv...
The cooling performance of the stack radiator of a fuel cell electric vehicle was evaluated under various actual road driving conditions, such as highway and uphill travel. The thermal stability was then optimized, thereby ensuring stable operation of the stack thermal management system. The coolant inlet temperature of the radiator in the highway mode was lower than that associated with the up...
In this paper, a data-based mechanistic modelling approach was developed to real time monitoring and online adaptive control of three-dimensional temperature distribution in both an individual biological product and in a given movement. Boxes of potatoes were used as biological material. During the experiments, step inputs on an air inlet temperature were applied while airspace and potatoes tem...
gas turbines play an important role in supplying power for the country especially in peak electricity load. the main disadvantages are the turbines, they produce large changes are a result of climate change. however, in times of peak electricity grid and at the same time warm months, can produce gas turbines under the effect of ambient temperature, the amount of reduced considerably. the method...
Stepwise regression method (SRM) was employed in order to develop simple and accurate models for prediction of supply air temperature and pad’s pressure drop of a cellulose evaporative cooling pad system. After validation of the obtained models, influence of variation of effective performance parameters on water and electricity consumption of a cooler which supplied a specific volume of c...
Modern engines are cooled by complex air and liquid cooling systems that manage the flow of high temperature air, gases and coolants, and house critical thermal management components. Plastics, many supplied by DuPont, are playing an increasingly important role in key cooling system parts including thermostat and heater housings, outlet and inlet ports, valves, cross-overs, coolant pumps, water...
Computational fluid dynamics (CFD) is potentially a valuable tool for simulating the dispersion of air contaminants in workrooms. However, CFD-estimated airflow and contaminant concentration patterns have not always shown good agreement with experimental results. Thus, understanding the factors affecting the accuracy of such simulations is critical for their successful application in occupation...
Abstract Energy crisis is a major challenge in the current world. Latent heat thermal energy storage (LHTES) systems are known as equipment with promising performance by which thermal energy can be recovered. In the present study a comprehensive theoretical and experimental investigation is performed on a LHTES system containing PEG1000 as phase change material (PCM). Discussed topics can be ca...
temperature restrictions on aqueous effluents dictate that streams with a temperature higher than the permitted level needed to pass through cooling systems to reduce the effluent temperature before discharge. in this study, by considering the grouping design rules based on pinch technology, an optimum design for a distributed effluent cooling system, has been developed. a counter-flow wet cool...
