Fluid mechanics: Properties of fluid, Laminar, and Turbulent Flow.Numerical Methods: finite volume method (FVM), finite element method (FEM), finite difference method (FDM).Partial differential equations, integration.Hence, C FD users have to be familiar with the following subjects as per their specific requirement. Computational fluid dynamics (CFD) is an interdisciplinary subject.Post-processing and results analysis: Predicted physical quantities need to be analyzed qualitatively and quantitatively.Simulation: Solving governing equations over a meshed model.Pre-processing: Creation of geometry and meshing.Computational fluid dynamics (CFD) comprises majorly three steps:.After solving iteratively using computer programs, engineers visualize predicted velocity, pressure and temperature. Numerical methods are used to convert partial differential equations in to algebraic set of equations. Governing equations are conservation of mass, momentum, heat and mass transfer. Computational fluid dynamics (CFD) is a technique of flow predictions by numerically solving governing equations of fluid flows.What is Computational Fluid Dynamics (CFD) Definition of CFD Modelings and Simulation is called as a third pillar of science and technology in the 21st century.Using the CFD technique, heat and mass transfer, reactive flow, multi-phase flow and combustion can be analyzed using various numerical models.Computational fluid dynamics (CFD) is a technique of modeling and simulation based on numerical modeling for fluid flow.It is useful to solve real world problems which can not be solved by theory and may be expensive by experimental analysis.Modeling and simulation is a technique to prediction the science and explore new knowledge.Modeling and simulation has emerged as a third pillar in many fields like engineering, molecular dynamics and astronomy.There are many limitations to get solutions for complex problems either by theory and experiments.Carrying out experiments is expensive, risky and time consuming.Experiment is conducted for simple cases to understand the details of objectives.Using theory and mathematical formulation we can solve simple problems in our real life and nature.Grid based Coupling of Pressure and VelocityĬFD Analysis of Laminar Flow Through the Circular Pipe.Which method (FDM/FEM/FVM) is the best suited for CFD Modeling?.Discretization of Computational Domain (Meshing).The general form of governing equation (in compact form) A caricature of physical transport phenomenon:.Fluid Flow with Fixed vs Moving Boundary.Compressible Flow vs In-compressible Flow.The regime for Laminar and turbulent Internal Flow.Comparison of Simulation and Experimental Analysis.What is Computational Fluid Dynamics (CFD).Introduction to Flow Analysis Techniques.When a person's Waist to Height Ratio is 0.63 and above in males and 0.58 and above in females, the person is said to be highly obese.When a person's Waist to Height Ratio falls between 0.58 and 0.63 in males and between 0.54 to 0.58 in females, the person is said to be extremely overweight.When a person's Waist to Height Ratio falls between 0.53 and 0.58 in males and between 0.49 and 0.54 in females, the person is said to be overweight for his/her age.When a person's Waist to Height Ratio falls between 0.46 and 0.53 in males and between 0.46 to 0.49 in females, the person is said to be a healthy individual.When a person's Waist to Height Ratio falls between 0.43 and 0.46 in males and between 0.42 to 0.46 in females, the person is said to be slender and healthy.When a person's Waist to Height Ratio falls between 0.35 and 0.43 in males and between 0.35 and 0.42 in females, the person is said to be extremely slim.When a person's Waist to Height Ratio falls below 0.35 in both males and females, the person is said to be abnormally slim.As a matter of fact, it is advisable to keep the waist circumference not more than half their height. The ratio uses the abdominal waist circumference close to the level of the navel or belly button. This is because the cardiometabolic risk can be lowered if the values are known well in advance. In the present scenario, several scientific studies rely on this ratio and prefer the Waist to Height Ratio over the BMI. Thus, our Waist to Height Ratio Calculator plays an indispensable role in knowing your Waist to Height Ratio. The values hold good for all age groups and for all statures. Higher values signal higher risk of medical complications that trigger serious health conditions like cardiovascular diseases, diabetes, stroke, obesity, and hypertension. Waist to Height Ratio (WHtR) also known as Waist to Stature Ratio (WSR) is used as an important gauge nowadays to tell a person if he or she is overweight or not. The functioning of this tool and the content on this page have been verified by iCliniq medical review team.
