i need support for my study task: a tiny rocket dia 4mm, length 60mm, needs a laminar flow that "sucks" the airflow into the center axis behind the projectile´s tail.
the task is 1. to show the "coanda" effect at different velocities (0-M3), and 2. how this effect can be locally disturbed by what forces applied, and 3. how the thrust jet is influenced/squeezed by the orthogonal pressure vector caused by the coanda effect.
please only apply if you are a fluid dynamics specialist.
so i propose these milestones:
create any rocket and fin-form form you want, od 4mm, length 60mm. show the "coanda" effect at different velocities (0-M3), show and measure the vector force pressing perpendicularly inwards, optimize the rocket´s round end in order to reach highest vector force over velocity range.
show how this effect can be locally disturbed by what forces applied to the rounded region in order to let laminar flow stall. think of a foil with a rough surface (range 0-50µm of ie bubbles) that you glue to that region. Eliminate as much as possible the “sucking” effect. Show best roughness geometry.
create a thrust that propels the rocket to M2.5-3 within ideally 20m. show energy used on 0-100m, acceleration chart and thrust and drag and weight chart. Use any useful powder and metal, that s not important. What I need is a realistic thrust with a realistic cone geometry.
show how the thrust jet is influenced/squeezed by the orthogonal pressure vector caused by the coanda effect and released w/o coanda effect. If the rough stall producing foil would be just half around the rocket s end: what would be the turn rate? Optimize the fins to produce highest and lowest turn rate.
