I am in need of simulating the airflow/drag of four different torpedo-shaped objects, as if they were moving through the air.

The work would involve constructing meshes for four simple cigar-shaped objects based on specifications provided, then run a CFD simulation of airflow so that drag can be analysed and compared.

Could you please provide some further information regarding dimensions, velocities, Re, Ma, etc. ?

The project is a public engagement exercise that asks the question: 'how far is it possible to throw a hotdog?' if it is thrown like an American football.

The object for CFD analysis is therefore a hotdog (in bread bun): four different designs will be made (e.g. a bun with a pointy end, a hotdog sausage that is fatter at the front, a bread bun that has fins...) for which a mesh will need to be generated. I would provide photos and measurements of the designs.

The CFD analysis needs to be able to create a visual output that can be used to show how airflow and drag generated by each hotdog differs. I see that such analyses have been performed previously for soccer and American footballs (e.g. https://www.simscale.com/blog/2014/0...n-in-football/ and https://www.resolvedanalytics.com/th...l-aerodynamics ) Results will need to be in a form that allows for some kind of quantitative comparison of drag between designs, and a prediction of which design will fly the furthest in ideal conditions.

I understand that such an application has varying speed and varying moving direction and thus not steady state, although for simplicity's sake a 'wind tunnel'-type steady-state analysis may be appropriate.

A hot dog? really? This gotta be all about marking
Anything more complicated than an effective drag ss subsonic calculation is way too expansive for its purpose... it should be a straightforward weekend task
