“…However, when the liquid sheet comes in contact with the encircling air causes a wave disturbance in the liquid sheet and once the wavelength reaches an optimum value fragments are generated in the sheet that will contract to ligaments due to the surface tension of the liquid and ultimately broken down into droplets [30]. The relation of diameter of the drop with respect to the properties of the liquid and air is given by D/δ ∝ We −0.5 (10) where, δ is thickness of the liquid sheet, We-Weber Number = ρU 2 δ/σ and U is the liquid sheet velocity.…”

Atomization is an intricate operation involving unstable and complex networks with rupture and fusion of liquid molecules. There are diverse details that typify the spray formation, which are the technique and configuration of the atomization process, dimension and structure of the nozzle, experimental parameters, etc. Ultimately, the process generates fine sprays from the bulk of a liquid. Some examples of atomization that we come across in our day-to-day life are antiperspirant or hair spray, shower head, garden sprinkler, or cologne mist. In this review paper we are briefly discussing the theoretical steps taking place in an atomization technique. The instabilities of the jet and sheet are explained to understand the underlying theory that breaks the jet or sheet into droplets. Different types of atomization processes based on the energy sources are also summarized to give an idea about the advantages and disadvantages of these techniques. We are also discussing the various biomedical applications of the electrohydrodynamic atomization and its potential to use as a drug delivery system. In short, this paper is trying to demonstrate the diverse applications of atomization to show its potency as a user friendly and cost-effective technique for various purposes.

“…They reported that burning synthesis gas leads to decreased performance by about 5% and to increased mass hourly consumption by 120 % [17]. Few researchers reported that the fluids injection has a crucial influence on the internal flows [18]. It is reported that the combustion duration of fuel increased significantly even with smaller concentration of honge oil in the fuel blend.…”

The biodiesel has lower volatility and is costlier than the fossil diesel. Hence it is necessary to add a low cost fuel which has higher volatility, with the diesel. The tire pyrolysis oil (TPO) produced from waste tire and tubes have these desirable properties and hence in this work, we have mixed TPO with biodiesel to enhance the properties of the biodiesel. The engine tests were carried out on a single cylinder compression ignition engine with the mixture of biodiesel and TPO as fuel. From the engine tests, it is observed that the fuel mixture results in engine performance close to diesel operation at the higher injector nozzle opening pressure.

Biodiesels from vegetable oils are also gaining momentum as a encouraging fuels which acts as alternative for agricultural diesel engines. Even though there is a slight penalty in the performance parameters by the usage of vegetable biodiesel fuels in diesel engines because of their high viscosity, there is considerable reduction in emissions which is dominant factor from the environmental perspective. In the present experimental work four fuels Canola (20% Canola oil plus 80% Diesel) biodiesel (B20C),Sesame (20% Sesame oil plus 80% Diesel) biodiesel (B20S), B20C blended with 5% n-butanol(B20C5B) and B20S is blended with 5% nbutanol(B20S5B) have tried as an alternative fuels to the Diesel. In the primitive stage tests were supervised on diesel engine with diesel. Thereafter in the second stage, tests were directed at identical operating conditions by using B20C, B20S and their blends as biodiesels. The engine important performance parameters brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) and also the emission characteristics hydrocarbons (HC), carbon monoxide (CO), smoke opacity and nitrogen oxides (NOx) are evaluated. The results are contrasted with respect on base line data (diesel). From the experimental readings it was observed that the BTE of B20C, B20S, B20C5B and B20S5B at 100% load decreased by 2.64%,1.9 %,1.41% and 0.94% respectively, relative to diesel (D). At maximum loading condition BSFC for diesel,B20C,B20S,B20C5B and B20S5B are 0.254, 0.284,0.273,0.270 and 0.260kg/kWh. Overall, it is concluded that the emission characteristics of HC, CO and Smoke opacity are dropped for all tested biodiesels when compared to diesel fuel.
