文摘
- •
A CFD model was developed to predict 尾-lactoglobulin denaturation in a plate heat exchanger.
- •
A k–蔚 turbulence model is well-suited for modeling plate heat exchanger hydrodynamics.
- •
The protein denaturation was measured before and after heat treatment at pilot-scale.
- •
The kinetic parameters provide a close correlation between the CFD model and experiments.
- •
The unfolded 尾-lactoglobulin species is the precursor of fouling in the exchanger.
