What is streamwise acceleration? How does it differ from normal acceleration? Can a fluid particle accelerate in steady flow?
Step 1 of 3<
p>Define streamwise acceleration and state the difference between the streamwise acceleration and normal acceleration. Step 2 of 3<
p>The streamwise acceleration
is defined as the component of acceleration of a particle of in the fluid along the streamline. The streamwise acceleration occurs due to the change of speed along the streamline.
In general the particle in fluid can have acceleration in any arbitrary direction. In two dimension, we can decompose the acceleration in two component, one along the streamline and other perpendicular to the stream line. The component along the streamline is called streamwise acceleration and the perpendicular component is normal acceleration.
