Discussion Overview

The discussion revolves around the potential existence of a field that applies molecular or atomistic modeling to fluid dynamics, specifically to predict macroscopic properties of fluids from molecular-scale computations. Participants explore the intersection of quantum mechanics and continuum mechanics, and the relevance of this modeling in various scientific disciplines.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant suggests that molecular/atomistic modeling could bridge quantum mechanics and continuum mechanics to predict fluid properties.
  • Another participant describes molecular modeling as solving Newton's 2nd law for closely spaced molecules, emphasizing the need for statistical analysis to derive larger-scale properties.
  • There is a mention of the importance of specifying system boundaries in fluid modeling, particularly for fluids under shear.
  • A participant questions whether the discussion pertains to electromagnetic properties or lattice dynamics, suggesting various theories in quantum mechanics that may be relevant.
  • One participant highlights that this area is active in chemical engineering, particularly in modeling flow properties of polymer melts and solutions, referencing a review article for further reading.

Areas of Agreement / Disagreement

Participants express different perspectives on the relevance and application of molecular modeling to fluids, with no consensus on a specific field or approach. The discussion remains open-ended regarding the exact nature of the research and its applications.

Contextual Notes

Participants mention various theories and fields without resolving the dependencies on specific definitions or assumptions related to fluid dynamics and molecular modeling.

I am wondering if there is such a subject as I am about to mention, I think it may be somewhere along the lines of computational fluid dynamics.

Molecular/atomistic modeling of the components of a fluid to determine the flow properties of that fluid. This is a topic that would bridge the gaps between quantum mechanics and continuum mechanics in order to predict macroscopic properties of fluids from theoretical computation at the molecular scale of the components of a fluid.

I know materials scientists incorporate molecular modeling of solid/crystal structures to determine the properties of a solid material. Is there a field that also applies these principles, except to fluids?

Which field of studies this sort of thing? Materials science? Physics? Chemical engineering? It sounds like chemical engineering transport phenomena to me, thought I have not taken that class yet

Thanks for your time

What you are talking about here is molecular modelling, solving Newton's 2nd law of motion for a large array of closely spaced molecules, based on the binary potential function for the molecules. This is usually followed by a statistical analysis to get the averaged properties on a larger scale. Lots of modelling work in this area has been done by chemists. For fluids that are experiencing shear, say, the motion of the system boundaries on the large scale need to be specified. Look for books on statistical thermodynamics of fluids, and on molecular modelling. You need to take a course in statistical thermo if you are going to work in this area.

If you are talking about electromagnetic properties, crystal properties etc and the link to quantum theory have you studied Bloch theory, Brilliouin theory, band theory, Debye theory and the theory of molecular orbitals in quantum mechanics?

Alternatively are you talking about lattice dynamics and defects?

For fluids look at plasma physics and magnetohydrodynamcs.

go well
 
This is a very active area in chemical engineering, particularly using molecular scale modeling to predict the for flow properties of polymer melts and solutions. About 10 years ago, they had a great review article in AIChE Journal discussing application of molecular modeling and statistical thermo to do these types of things. Look for articles by Stanley Sandler.
