(383e) Upscaling of Pore-Scale Simulations
AIChE Annual Meeting
Tuesday, November 9, 2021 - 4:54pm to 5:15pm
I will first present a validation of the physical model, by comparing simulations of a dissolving cylinder with the results of a microfluidic experiment and a conformal mapping simulation. Then I will describe ongoing work, which uses insights drawn from simulations of arrays of disks to suggest ways of upscaling in cases where dissolution is predominantly transport controlled. Numerical simulations show that a multiplicative decomposition is in good agreement with simulations. The final step is a distance-dependent rescaling of the time, which allows different REV's (Representative Element Volume) in the array to be mapped to the dissolution of a single REV.
