Question

When the concept of continum approximation became questionable?

Answer 1

The continuum approximation is a mathematical idealization for modeling the collective response of discrete systems. ... Given the continuum approximation of a system, homogenization theory further provides a method for recovering the solution of the original discrete or heterogeneous system

Answer 2

Answer: Instead, need to define a representative elementary volume (REV) to average quantities like velocity ... Too small: bad averaging. • Too big: ... This cannot be reconciled in continuum approach, so must be modeled. This is the ..... number of simplifications that enable analytical approximations for common flows, as well as.
