The design of the vaned diffuser of a centrifugal compressor is still based on a considerable amount of empiricism in its design methodology. Parameters such as area ratio and blockage, which are more relevant to conical diffusers, are used in conventional design practice.
Seek your input on nano-indentation or basic mechanics of materials
Dear researchers----We spent more than two years to prepare a research proposal and it was submitted to a federal funding agency (not NSF). Based on one reviewer’s comments, the program manager rejected our proposal. Our title is “A Multi-Scale Approach of Combining Nano-indentation with Computational Mechanics to Predict Impact Behavior of Structural Composite Materials”. I only list these comments related to nano-indentation. Your frank opinion is really appreciated.
