Differences of Dimensions in Analysis

  1. Nov 10, 2006 #1
    When analyzing/studying thermochemistry or any system with gases, i.e., combustion, fusion, fuel cells, often time in the literature the system is derived or modelled as being zero-dimensional or quasi-one dimensional.
    Can anyone provide a good explanation as to the differences between 0, 1, and quasi-1 dimensions or explain what the use of this mathematics gains you in analyzing/studying gaseous systems?

    As an example: concerning combustion modeling using turbulent kenetic energy densities and fuel concentrations where the author is using a zero-dimension for analysis.

    "...this formulation based on the k-ε model commonly used in three-dimensional simulations is not particularly suitable for zero-dimensional models."

    Again, can anyone provide a good explanation as to the differences between 0, 1, and quasi-1 dimensions or explain what the use of this mathematics gains you in analyzing/studying gaseous systems?
