Laminar and Turbulent Flow

Laminar and Turbulent Flow

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...

Steady, Laminar Flow Between Parallel Plates

Steady, Laminar Flow Between Parallel Plates

Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.

Area of Science:

Biomedical optics
Computational modeling
Fluid dynamics

Background:

Monte Carlo simulations are crucial for modeling light propagation in turbid media for biomedical applications.
Existing voxel-based platforms struggle with curved boundaries and limited customization of flow and scattering properties.
Through-transmission laser Doppler flowmetry (LDF) in highly scattering samples is underexplored, despite relevance for lab-on-a-chip and inline flow sensing.

Purpose of the Study:

To develop a novel voxel-free Monte Carlo simulation platform, MC-Doppler, for through-transmission LDF in highly scattering media.
To validate the simulation's accuracy by comparing simulated and experimental Doppler power spectra.

Main Methods:

Developed MC-Doppler using unit vectors and ray tracing for light propagation.
Implemented fully customizable scattering phase functions and flow fields.
Tested the platform with polystyrene bead suspensions in a glass tube at various flow rates (0-15 mL/min).

Main Results:

Simulated and experimental Doppler power spectra showed good agreement for scattering coefficients up to 5 mm⁻¹.
Discrepancies were observed near scattering coefficients of 10 mm⁻¹.

Conclusions:

MC-Doppler provides accurate simulations of light propagation for through-transmission LDF.
The platform is effective for moderate scattering coefficients, advancing flow quantification in challenging biological fluid applications.
