What is fluid dynamics?
Click to flip
Fluid dynamics is the study of the flow of fluids (liquids and gases) and focuses on how forces interact with these fluids.
Click to flip
What is the difference between laminar and turbulent flow?
Click to flip
Laminar flow is characterized by smooth, parallel layers of fluid, whereas turbulent flow involves chaotic and irregular fluid motions.
Click to flip
What is viscosity in fluid dynamics?
Click to flip
Viscosity is a measure of a fluid's resistance to deformation or flow.
Click to flip
What is Bernoulli's principle?
Click to flip
Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.
Click to flip
What is a fluid's Reynolds number?
Click to flip
Reynolds number is a dimensionless number used to predict flow patterns in different fluid flow situations.
Click to flip
What does the continuity equation in fluid dynamics state?
Click to flip
The continuity equation asserts that the mass flow rate must remain constant in a steady, incompressible flow.
Click to flip
What is the role of fluid dynamics in weather prediction?
Click to flip
Fluid dynamics helps model atmospheric and oceanic flows, crucial for predicting weather patterns.
Click to flip
What is the significance of the Navier-Stokes equations?
Click to flip
The Navier-Stokes equations describe the motion of fluid substances and are fundamental in fluid dynamics.
Click to flip
How does fluid dynamics apply to blood flow in the human body?
Click to flip
Fluid dynamics helps in understanding the flow of blood through the circulatory system, affecting how efficiently nutrients are delivered throughout the body.
Click to flip
What is the role of computational fluid dynamics (CFD)?
Click to flip
CFD uses numerical analysis to simulate fluid flow and is a crucial tool in engineering and design optimization.
Click to flip
What is a boundary layer in fluid dynamics?
Click to flip
A boundary layer is a thin layer of fluid at the boundary of a solid where fluid velocity changes from zero to a free stream value.
Click to flip
How is drag force related to fluid dynamics?
Click to flip
Drag force is the resistance experienced by an object moving through a fluid and is a key concept in fluid dynamics.
Click to flip
What is flow separation in fluid dynamics?
Click to flip
Flow separation occurs when the fluid flow detaches from the surface of an object, often leading to increased drag and reduced lift.
Click to flip
What is the principle of inertia in fluid dynamics?
Click to flip
Inertia in fluid dynamics refers to the tendency of a fluid to resist changes in its state of motion.
Click to flip
Why is fluid dynamics important in environmental engineering?
Click to flip
Fluid dynamics is vital for modeling and managing water resources, pollution tracking, and designing efficient water treatment systems.
