To the problem existing freezing test equipment unable to satisfy the demand of experimental research study on test technique of ice accretion. This paper firstly introduces two kinds of conventional icing scaling method: Olsen method and AEDC method ( Ruff ); Then using the mixed scale test model do icing test, mainly uses the simple cylindrical models do a simplified testing, thus validating the feasibility of AEDC (mixed shrinkage ratio test model ) method; Finally, in accordance with the designed airfoil mixed models for numerical simulation, thus further proved the feasibility that the hybrid scaled models instead of the original size model. The test established a scaled theory basis for numerical simulation on hybrid complex models, thereby validated the feasibility of the icing research method.

“…Icing on an airfoil or craft is defined as that condition where supercooled water droplets freeze on airframes or airfoil and form amount of ice which disturbs the airflow. In recent years, the number of icing related accidents has stimulated a renewed interest in the effect of icing on aerodynamic performance of aircraft (Anderson, et al, 2001). The formation of ice on aircraft components such as wings, control surfaces and engine intakes, occurs when the aircraft flies at a level where the temperature is at, or below freezing point and hits supercooled water droplets and (Anderson and Ching, 2003 ).…”

A numerical investigation was conducted to study the effect of simulated ice accreted on airfoilaerodynamics performance. The simulated ice shapes were tested on NACA 0012 airfoil wing atdifferent Mach numbers. The study includes the one of the famous types of ice accreted on theairfoils called the rime ice.The calculation of ice droplet trajectories was performed by solving the trajectories governing equations of the droplet using FVM. A numerical model based on staggered FVM is built up to solve the governing equations of a body fitted grid, trajectories equation, continuity equation and momentum equation using FORTRAN 97. The turbulence model of (k-ε) has been adopted in the programming to evaluate the turbulence effect. The program is valid for any type of 4 or 5 digits airfoil. The program is available to evaluate the rime ice accumulation. The pressure, lift, drag and pitching moment coefficients are computed and compared with that of clean case results. The program was run over different Mach numbers, to compare the results obtained at these Mach Numbers. The investigation of the work was tested on NACA 0012 in a range of angle of attack 0º to 6º, where stall starts at this angle of attack as demonstrated by the results. The results show that the severity of ice formation could be more dangerous with increasing the angle of attack or the Mach number.
