specific impulse from liquid rocket engines. Combustion takes place in gaseous phase and reaction is fast. So, the
time consumed by a droplet for complete burning is the time taken by a droplet to get evaporated. An analytical
mono component fuel droplet evaporation model is developed and proposed for droplet evaporation in liquid rocket

of mixing mineral oil at certain proportions with vegetable oil is discussed its use as commercial lubrication oil is
also outlined, The tribological attributes are investigated through the well known four ball tribotester method. In the
experiments, castor oil is blended at volumetric ratio ranging from 20 to 80 % with commercial mineral oil...

combustion technique. Effect of mesh size, primary and secondary air velocity at various air fuel ratios was investigated
to quantify the combustion performance by measuring the furnace temperature. Mesh size 200 was found to
be readily combustible within the operating ranges, while tight control of the operating parameters was required
to combust coal at mesh size 150. Optimum r...

combustion chamber (CC) are better than sac nozzles with hemispherical CC, and that wider cone angle nozzles
at 10° BTDC give the optimum results in terms of emissions and performance, relative to those of narrower cone
angles. The 150° nozzles with 1.5 mm tip penetration give abated carbon monoxide (CO), hydrocarbon (HC) and
smoke emissions along with better performance characteristics such as brake specif...
