Question

Explain five differences between Laser Doppler Anemometer LDA) and Particles Image Velocimetry (PIV). Describe a micro-PIV technique in determining two-dimensional (2D) liquid flow profile in a microchannel. Specify all the instruments and seeding requirement. Describe the expected results from the experiment. Fluorescent polystyrene microbeads are used in a flow visualization and separation efficiency determination in a spiral microchannel inertial focusing experiment. Without using a micro-PIV technique, explain the setup in conducting this experiment. How the fluorescent particle size selection is determine?
