“…Various studies have been analyzed on biodiesel production from vegetable oils and algal oils in recent years. Many researchers have conducted experimentation on fuel blends up to 20 per cent (Channappagoudra et al, 2018;Jiotode and Agarwal, 2016;Dhar and Agarwal, 2014) and have suggested on increasing the biodiesel blend to analyze the combustion phenomenon and also to inspect the emission characteristics (Vijay Kumar et al, 2018;Hosseinzadeh-Bandbafha et al, 2018). Accordingly, the present research article investigates the combustion characteristics of straight biodiesel in compression ignition engine and compares with mineral diesel.…”

Purpose Vast areas have been studied toward combustion and emission analysis in vegetable oil methyl esters and quite a few in algal oil biodiesel. To analyze the better alternate source for diesel engine, this study aims to investigate the combustion behavior and emission characteristics between cottonseed biodiesel and algal oil biodiesel on comparison with mineral diesel in a compression ignition engine. Design/methodology/approach The fuel properties like density, kinematic viscosity, calorific value and Cetane number have met the biodiesel standards for both algal and cottonseed biodiesel. At rated power, engine was operated on all three test fuels, where combustion analysis describing in-cylinder pressure, peak pressure, rate of pressure rise and rate of heat release and emission characteristics including hydrocarbon (HC), carbon monoxide (CO), oxides of nitrogen (NOx) and smoke for both biodiesel comparing mineral diesel. Findings Algal and cottonseed biodiesel showed up to 2-3°CA delayed start of combustion comparing mineral diesel curve. The in-cylinder pressure of algal biodiesel was found to be 68 bar, whereas cottonseed biodiesel exhibited 65 bar at full load condition. Similarly, the rate of pressure rise and rate of heat release of algal biodiesel depicted 7.9 and 10.7 per cent rise than cottonseed biodiesel, respectively. As the load increased, ignition delay showed decreasing trend, while combustion duration showed an increasing trend. HC, CO and smoke emissions were seen to be lower than mineral diesel with noticeable increase in NOx emission. Originality/value In this present investigation, biodiesel from Stoechospermum Marginatum, a marine marco algae, was used to fuel the compression ignition engine. Its combustion behavior and emission characteristics are compared with cottonseed biodiesel, a vegetable oil-based biodiesel having similar physio-chemical characteristics to understand the suitability of algal biodiesel in compression ignition engine. This study involves the assessment of straight biodiesel from macro algae and cottonseed oil on standard operating conditions.

In this investigation, Jojoba bio-oil was converted to biodiesel through a process of transesterification. In the present work methanol is used as an alcohol and potassium hydroxide is used as a catalyst. Single stage transesterification process was employed as the content of free fatty acids was 1.2%. Physiochemical properties of the biodiesel like density, specific gravity, calorific value, flash and fire point, ash content, kinematic viscosity and acid value were found out using different methods and these properties are compared with those of petroleum diesel

“…Ishida et al [9] studied the velocity distribution at exit of the impeller for a varied tip clearance conditions involving two types of unshrouded centrifugal impeller. Similarly, several studies [10][11][12][13][14][15][16][17][18][19] were carried out by researchers on understanding the flow field at centrifugal impeller exit and reported ways to improve the performance of centrifugal compressor by suppressing the impact of the separation zone.…”

Abstract: The flow through centrifugal impeller is highly non uniform due to formation of regions with different energy level. These region mixes at the exit of the impeller leading to loss and bringing down the efficiency of the centrifugal impeller. The present study focus on analyzing the flow through an impeller and investigating the impeller exit flows. The simulations are carried out for various mass flow rates at design and off design conditions. The velocity vectors observed depicts the regions of jet along the pressure side and wake at the suction side. The contours of total pressure and velocity depict the diffusion process that occurs within the impeller and its exit. Non uniform flow is observed along the circumferential direction of the impeller. These non uniform flow leads to secondary flow as well as loss in total pressure thereby reducing the efficiency of the centrifugal impeller.
