WebFeb 9, 2024 · When considering propellers, many boat owners get fixated on speed. They assume a prop that will make their boat go faster must be better. It’s more important to consider how a propeller can impact the entire boating experience. Speed is one element of that experience, but so are acceleration, economy, comfort and boat handling. WebWe model the flow through the propeller as shown in Figure 11.26 and make the following assumptions: Neglect rotation imparted to the flow. Assume the Mach number is low so that the flow behaves as an incompressible fluid. Assume the flow outside the propeller streamtube has constant stagnation pressure (no work is imparted to it).
