A hybrid Heat Transfer Coefficient (HTC) model has been developed based on the Surface Renewal Theory and implemented into a system code. The model accounts for both large and small eddies for the removal of heat from the two-phase interface towards the subcooled liquid bulk. The hybrid approach for the calculation of the Surface Renewal Period will increase the applicability region of the individual Surface Renewal Theory (SRT) based HTC for various flow regimes. Validation of the new Hybrid HTC model is performed against experimental data.
