Which way is the wind flowing???

Scenarios on a boat with hull speed of 8 knots.

Reaching at 10-15 knots TWS: Wind flow fore to aft.

Broad Reach 10-15 knots TWS: Winds flows aft forward?

Reaching at 30-35 knots TWS: Wind flows fore to aft, sorta.

Broad Reach at 30-35 TWS: Wind flow aft forward for sure.

Whaddya think? What's the flow looking like at the angles and wind speeds? Is the flow tearing away at high speed on the Reach or not? I don't have telltales on my sails and just sail by the cloth so I can't say for certain what the wind is really doing flow wise in these situations.
