Further exploration of acoustic droplet vaporization - Coggle Diagram
Further exploration of acoustic droplet vaporization
Objectives
(1) Simulate single droplet vaporization with existing models but applied to BRG droplet such as condensed BR38 or microfluidic PFC nanodrops
(2) Define a robust method for pressure threshold determination
(3) Apply design of experiments for multivariate characterization of the phenomenon
Strategies
Statistical threshold determination methods
Multiple designs : Doehlert for exploration then central composite for quality
Lacour's model implementation
Factors
Hyper-parameters of fit
Acoustical
Excitation frequency
Number of cycles per pulse
Parameters
Formulation
C5F12
