Implementation and assessment of wall friction models for LWR core analysis

ANNALS OF NUCLEAR ENERGY, 115, 565–572.

By: A. Toptan n, N. Porter n, R. Salko * & M. Avramova n 

author keywords: Friction factor; CTF; Pressure drop; Subchannel analysis; Validation; Verification
topics (OpenAlex): Heat transfer and supercritical fluids; Nuclear Engineering Thermal-Hydraulics; Nuclear reactor physics and engineering
TL;DR: The modeling of frictional pressure drop in the nuclear thermal hydraulics subchannel code, CTF, is improved through the addition of three new modeling options which allow the code to account for the effects of surface roughness and the third enables a user-supplied option.
