Hi Shreen,
To illustrate fluid flow within the cylindrical geometry, an effective approach is to introduce an inner cylinder that represents the fluid. This inner core can be visually distinguished using a different colormap and some transparency, helping it stand out from the outer structure.
For example:
t = 0:pi/20:2*pi;
[Xf, Yf, Zf] = cylinder(0.6 * (1 + 0.06 * sin(5 * t)));
Zf = Zf * 3;
fluid = surf(Xf, Yf, Zf, Zf, 'FaceAlpha', 0.6, 'EdgeColor', 'none');

To enhance the visualization and simulate fluid motion, animate the inner surface by gradually shifting the phase of the sine wave. This creates a wave-like effect, simulating fluid movement inside the cylinder:
for k = 1:100
[Xf, Yf, Zf] = cylinder(0.6 * (1 + 0.06 * sin(5 * t + 0.1 * k)));
Zf = Zf * 3;
set(fluid, 'XData', Xf, 'YData', Yf, 'ZData', Zf, 'CData', Zf);
drawnow;
end
