Fuel droplet evaporation involving heat and mass transport holds key interest due to its industry wide applications. This paper presents a novel experimental investigation of an isolated fuel droplet and tandem droplets array evaporation. Acetone droplets of 2120μm diameter were supported on 300|im diameter glass fiber to investigate under hot forced convection ambience. Planar laser induced fluorescence (PLIF) was used to estimate the vapor concentration around the evaporating isolated droplet and droplets array. An attempt was made to estimate the vapors concentration around and behind the evaporating droplets. The depletion of vapor concentration for isolated droplet was found to be more than the leading droplet in droplets array. The wake of the trailing droplet was longer than the isolated droplet wake. The effect of leading droplet was evident on the trailing droplet life time and size.
