Summary
Computational fluid dynamics (CFD) software, MECOMLAND® and NOSELAND®, offers intuitive nasal airflow analysis for rhinologists. This non-invasive tool aids in diagnosing and managing nasal pathologies with enhanced precision and patient safety.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Computational Science
Background:
- Computational fluid dynamics (CFD) is an advanced analytical tool for airflow analysis.
- CFD is not yet a standard tool for rhinologists, limiting its application in nasal airflow studies.
- There is a demand for intuitive, precise, and powerful CFD software for evaluating nasal airflow.
Purpose of the Study:
- To introduce MECOMLAND® and NOSELAND®, user-friendly CFD software designed for rhinologists.
- To provide a non-invasive, low-cost alternative for functional nasal airflow studies.
- To validate the software's efficacy in differentiating nasal airflow characteristics between normal and deviated septa.
Main Methods:
- Developed MECOMLAND® software utilizing patient tomographic images for CFD analysis.
- Integrated NOSELAND® for user-friendly post-processing with 3D endoscopic views and dynamic reports.
- Validated software by comparing CFD-derived parameters (wall shear stress, velocity, pressure drop, flow rates) in patients with normal noses versus those with septal deviations.
Main Results:
- MECOMLAND® and NOSELAND® provide quantitative airflow data including distributions, velocity, pressure, temperature, and wall shear stress.
- Wall shear stress was found to be lower in normal noses compared to those with septal deviations.
- Significant differences in velocity field distribution, pressure drop, and flow rates were observed between normal and deviated nasal cavities.
Conclusions:
- MECOMLAND® and NOSELAND® software effectively meet the demand for intuitive and precise CFD analysis in rhinology.
- These tools offer a valuable, non-invasive method for the functional study of complex rhinologic cases.
- The software holds promise for simulating virtual surgical interventions and understanding airflow dynamics under various conditions.

Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures enhance...

Laminar flow occurs when a fluid moves smoothly in parallel layers with minimal mixing and turbulence. In fluid mechanics, ensuring laminar flow within a pipe is essential for precise control of flow characteristics, especially in engineering applications. The key factor in determining whether flow remains laminar is the Reynolds number, a dimensionless quantity that depends on the fluid's velocity, density, viscosity, and the pipe's diameter. A Reynolds number of 2100 or lower...

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...

The process of breathing involves the periodic intake and expulsion of air, known as the respiratory cycle, which typically lasts about five seconds. Modeling the volume of air inhaled into the lungs as a function of time provides insight into both the dynamics and efficiency of pulmonary ventilation. This volume is determined by integrating the airflow rate over time, which captures the cumulative effect of air entering the lungs.Sinusoidal Model of AirflowAirflow during respiration is not...

When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

Turbulent flow is characterized by unpredictable fluctuations in velocity and pressure, which result in a chaotic fluid movement distinct from the orderly patterns of laminar flow. While laminar flow is governed by smooth, parallel layers with minimal mixing, turbulent flow exhibits highly irregular, three-dimensional patterns. This behavior arises due to instabilities in the fluid's velocity profile, and amplifies as the flow velocity increases. Minor disturbances, known as turbulent...
