Numerical Validation of Conjugate Heat Transfer Method for Anti-/De-Icing Piccolo System

摘要

An anti-/de-icing conjugate heat transfer method based on a ANSYS-CFX flow solver and FENSAP-ICE software is presented. The ANSYS-CFX flow solver is used as the flow solver module with the k-ω shear stress transport turbulence model. DROP3D is used as the droplet impingement module. ICE3D is used as the ice accretion and water film runback module. CHT3D/CFX is used for the thermal coupling of all modules. Before solving for the temperature distribution in a three-dimensional antiicing system geometry based on a piccolo tube with three jet rows, a test case consisting of a two-stream parallel gas-to-gas microheat exchanger will validate the CHT3D/CFX procedure. For the antiicing system in wet air mode, the temperature results at corresponding experimental locations are presented and compared to results from the literature.
