Sample interview questions: Have you ever used computer simulations to model physical phenomena? If yes, please provide an example.
Sample answer:
Yes, I have extensively utilized computer simulations to model physical phenomena across various domains. One notable example is my work on simulating the flow dynamics of complex fluids using computational fluid dynamics (CFD) techniques.
In one particular project, I employed the open-source CFD software OpenFOAM to simulate the behavior of a non-Newtonian fluid flowing through a microfluidic channel. Non-Newtonian fluids exhibit nonlinear and time-dependent rheological properties, making their flow behavior highly complex and challenging to predict analytically.
To accurately capture the fluid’s behavior, I incorporated a tailored constitutive model into the CFD simulations. This model accounted for the specific viscoelastic and visco-plastic properties of the fluid. I meticulousl… Read full answer
