Abstract
A method of forming an ice resistant surface includes determining, based at least in part on a desired pattern of frost formation, a vertex angle for a ridge that is to be formed on a substrate. The method also includes determining, based at least in part on the desired pattern of frost formation, a vertex height for the ridge that is to be formed on the substrate. The method further includes forming a plurality of ridges on the substrate, where each ridge in the plurality of ridges has the vertex angle and the vertex height.

A method of forming an ice resistant surface comprising:
- determining, based at least in part on a desired pattern of frost formation and a desired distribution of diffusion flux magnitude, a vertex angle for a ridge that is to be formed on a substrate;
- determining, based at least in part on the desired pattern of frost formation, a vertex height for the ridge that is to be formed on the substrate;
- and
- forming a plurality of ridges on the substrate, wherein each ridge in the plurality of ridges has the vertex angle and the vertex height.
A system for forming an ice resistant surface comprising:
- a memory configured to store information regarding relationships between vertex angles and frost formation patterns;
- a processor operatively coupled to the memory and configured to:
- determine, based at least in part on a desired pattern of frost formation and a desired distribution of diffusion flux magnitude, a vertex angle for a ridge that is to be formed on a substrate;
- and
- determine, based at least in part on the desired pattern of frost formation, a vertex height for the ridge that is to be formed on the substrate;
- and
- a mold that includes a plurality of ridges and that is configured to form the plurality of ridges on the substrate, wherein each ridge in the plurality of ridges has the vertex angle and the vertex height.
