“…While reciprocating engines are very sensitive to problems such as clogging and delayed ignition, gas turbines have shown good potential to cope with alternative fuels. Experimental studies have shown that most common biofuels, such as bioalcohols and biodiesel, can already be burned in pure form in standard or slightly modified combustor designs without any significant problems [4][5][6][7][8][9].…”

The present investigation deals with the puffing and micro-explosion characteristics in the combustion of a single droplet comprising butanol/Jet A-1, acetone-butanol-ethanol (A-B-E)/Jet A-1 blends, and A-B-E. The onset of nucleation, growth of vapor bubble and subsequent breakup of droplet for various fuel blends have been analyzed from the high-speed images. Puffing was observed to be the dominant phenomenon in 30% butanol blend, while micro-explosion was found to be the dominant one in other fuel blends (blend with 50% butanol or 30% A-B-E or 50% A-B-E). It was observed that puffing always preceded the micro-explosion. The probability of micro-explosion in droplets with A-B-E blends was found to be higher than that of butanol blends. Although the rate of bubble growth was almost similar for all butanol and A-B-E blends, the final bubble diameter before the droplet breakup was found to be higher for 50/50 blends than that of 30/70 blends. The occurrence of microexplosion shortened the droplet lifetime, and this effect appeared to be stronger for droplets with 50/50 composition. Micro-explosion led to the ejection of both larger and smaller secondary droplets; however, puffing resulted in relatively smaller secondary droplets compared to micro-explosion.Puffing/micro-explosion were also observed in the secondary droplets.

“…Numerous publications can be found in the literature (Ali and Nour 2017;Badami et al 2014;Baranski et al 2011;Canteenwalla et al 2016;Cavarzere et al 2014;Chiaramonti et al 2013;Chiariello et al 2014;Chishty et al 2011;Habib et al 2010;Hoxie and Anderson 2017;Ibrahim et al 2013;Mendez et al 2014), which are associated with testing different fuels with the use of small-scale turbine engines. It is worth emphasizing that currently fuels containing synthesized hydrocarbons obtained through five specific paths described in ASTM D7566-16 (2009) are approved for direct use as synthetic blending components (up to 50%) in aviation turbine fuels.…”

It is forecast that in the future, alternative fuels derived from non-petroleum sources will become the basic propellant for turbine aircraft engines. Currently, five types of aviation turbine fuel containing synthesized hydrocarbons are certified and accepted, and allow adding a maximum of 50% of synthetic component to conventional fuel. The experimental performance and the emission characteristics of a turbojet engine were investigated in this paper. The studies were conducted with the use of a miniature turbojet engine, which is the main component of a laboratory test rig. The test rig is an interesting solution for engine research, due to the fact that studies concerning fullscale aircraft engines are very complex and expensive. The literature of the subject contains many papers using smallscale turbojet engines for testing alternative fuels. However, most of them concern components of fuels, e.g. biodiesel, butanol, which do not have direct application in aviation. Two different fuel samples, a conventional Jet A-1 fuel and a blend of 48% synthesized paraffinic kerosene from hydroprocessed esters and fatty acids process with Jet A-1 were tested. This process is one of the routes of producing alternative fuel for aviation, approved by ASTM standard. The test rig studies were performed according to a specific profile of engine test, which models different modes of a turbojet engine's operation. The obtained results are compared in relation to the results for neat Jet A-1 fuel and then discussed.
