Encoding Molecular Dynamics for Flow Regime Control in Cerebrospinal Fluid: From Macroscopic Navier-Stokes to Microscopic Influences
Abstract
Chur Chin
The ultimate control and manipulation of fluid flow regimes, particularly the transition between laminar and turbulent states, hold immense potential, especially in sensitive biological systems like cerebrospinal fluid (CSF) circulation. This paper proposes exploring theoretical methodologies for encoding the rotational and vibrational dynamics of water molecules into fluid models to understand, and potentially influence, these flow changes. While the Navier-Stokes equations govern macroscopic flow driven by gravity and pressure, their continuum nature inherently averages out molecular details. We will examine how micro continuum theories and non-Newtonian fluid models serve as crucial conceptual bridges, attempting to incorporate the macroscopic manifestations of these molecular behaviors. Although direct quantum-level encoding into standard fluid dynamics equations remains an unsolved challenge, the indirect influence of quantum mechanics on viscosity is paramount. This exploration will illuminate how molecular properties, when effectively “encoded” through advanced rheological models, could theoretically drive shifts in CSF flow behavior, alongside a critical assessment of the limitations of current theoretical frameworks in achieving such precise control.
