A physics-based model for frost buildup under turbulent flow using direct numerical simulations

N Zgheib, M Farzaneh, S Balachandar… - International Journal of …, 2022 - Elsevier
We present a new model for frost buildup under turbulent (and laminar) flow using direct
numerical simulations. The physical model consists of two layers, the air and the frost. The …
