Combustion characteristics of alternative liquid fuels
… airblast atomizer are investigated using a phase Doppler anemometry (PDA) under non-reacting conditions. The droplet size and velocity distribution of biodiesels are compared to conventional fuels. For spray combustion investigations, a generic gas turbine-type combustor is developed to …

Investigation of cutting temperature and cutting force from mist flow pattern in MQL technique
… were selected based on the results obtained from Phase Doppler Anemometry (PDA). The machining performance was evaluated under three levels of cutting speed and two levels of feed rate at constant depth of cut. The cutting force was measured using a set of dynamometer and cutting temperature using …

Design and Numerical Simulation of the Real-time Particle Charge and Size Analyser
… (PSCA), investigated in this thesis, uses Phase Doppler Anemometry (PDA) technique. The PDA system was used to track the motion of charged particles in the presence of an electric field. By solving the equation of particle motion in a viscous medium combined with the simultaneous …

Spray visualization and characterization of a multi variable circular orifice (MVCO) injector coupled with a swirl adapter for diesel reformer applications
… from both the front view and the bottom view. Phase Doppler Anemometry (PDA) measurement was conducted at different locations in the spray for the acquisition of droplets size and velocity distribution. Difficulties in measurements were encountered for high pressure injection, especially in the …

Multihole injectors for direct-injection gasoline engines
… velocity and diameter with a two-component phase-Doppler Anemometry (PDA) system at injection pressures up to 200bar and chamber pressures varying from atmospheric to 12bar. The overall spray angles relative to the axis of the injector were found to be almost independent of injection and …

A study on the characteristics of the flow inside a thermostatic expansion valve
… cone angle and film thickness determination. A Phase Doppler Anemometry (PDA) system was used later to measure the size and velocity of individual droplets passing the location at the outlet of the orifice. It is found that the increase of the feeding pressure tends to expand the spray cone …
