Whatever the case, a well-established methodology exists to describe this deviation from standard diffusive transport (with characteristic scales): the [[Continuous Time Random Walk]] (CTRW) model. | Whatever the case, a well-established methodology exists to describe this deviation from standard diffusive transport (with characteristic scales): the [[Continuous Time Random Walk]] (CTRW) model. | ||

The CTRW model provides a mathematical framework for handling non-diffusive transport (arising as as generalisation of the diffusive transport when eliminating the stated characteristic scales), but it does not explain why such non-diffusive transport should arise: answering the latter requires detailed computer simulations of turbulence and experimental observations. | The CTRW model provides a mathematical framework for handling non-diffusive transport (arising as as generalisation of the diffusive transport when eliminating the stated characteristic scales), but it does not explain why such non-diffusive transport should arise: answering the latter requires detailed computer simulations of turbulence and experimental observations. | ||
