Description
Summary:A system of liquid water content equations is discussed along with numerical approach based on Galerkin method with discontinuous basis functions of high accuracy. Systematic study is performed to verify its effectiveness for the NACA0012 airfoil test case with emphasis on the collection efficiency. Quasy-steady thermodynamic model of mass and heat balance is described for control volume built on surface element. Numerical solution to the system of balance equations for control volumes gives their thermodynamic states, including mass and heat flows, balance temperature, ice growth rate. Test cases for moist gas flow around the NACA0012 airfoil and the GLC-305 wing are considered. Computed ice shapes obtained with assumption of “thin ice” for different regimes are compared to the experimental data to validate the adequacy and the accuracy of models and algorithms. Conclusions about application of high accuracy method and forecasting the ice accretion on aircraft elements with proposed approach are given.
