50ft oh casts, comparison of alternative angular accelerations

Purpose

The purpose of this comparison is to show the impact of changing the angular rod accelerations.

The comparison is made between two simulations:

· The 50ft oh ref. cast with an increasing acceleration (angular velocity quadratically increasing with time).

· Constant acceleration (angular velocity linearly increasing with time).

Input, casting stroke

The angular velocity, shown for the two cases below, is the only input that differs between the two compared cases.

Input, equipment

The equipment for both simulations is identical, see the 50ft oh ref. cast.

Output, animation

Comments, animation

The cast with constant angular acceleration gives a slightly wider loop (larger loop apex radius) and reduced loop speed indicating that an increasing angular acceleration is better, at least for the equipment used.

Output, graphs

The graphs considered most relevant for the comparison are presented below. For explanations to the graphs please see the 50ft oh ref. cast.
