ABSTRACT:
An integrated software package, ICEG2D, was developed to automate computational fluid dynamics (CFD) simulations
for singleelement airfoils with ice accretion. ICEG2D is designed to automatically perform three primary functions: (1) generating a gridready, surface definition based on the geometrical characteristics of the iced airfoil surface, (2) generating a highquality grid using the generated surface point distribution, and (3) generating the input and restart files needed to run the general purpose CFL) solver NPARC. ICEG2D can be executed in batch mode using a script file or in an interactive mode by entering directives from a command line. This report summarizes activities completed in the first year of a threeyear research and development program to address issues related to CFD simulations for aircraft components with ice accretion. Specifically, this document describes the technology employed in the software, the installation procedure, and a description of the operation of the software package. Validation of the geometry and grid generation modules of ICEG2D is also discussed.
