The Wind Off the Small Isles Only two days after arriving there, Cora decides she wants to buy a house. While driving around the island they reach Playa Blanca and Cora sees just the house she is looking for. She sends Perdita to ask who owns it. Perdita, after getting no answer at the front door, meets Michael in the grounds who is supervising building work. There is a mention of Julian Gale from Stewart's earlier novel, "This Rough Magic". The Wind Off the Small Isles The Wind Off the Small Isles is a novella by Mary Stewart, first published in 1968. Unlike her other works,
Subsonic and transonic wind tunnel interactions occur (such as shock waves or boundary layer interaction) both Mach and Reynolds number are important and must be properly simulated. Large-scale facilities and/or pressurized or cryogenic wind tunnels are used. With a sonic throat, the flow can be accelerated or slowed down. This follows from the 1D area–velocity equation. If an acceleration to supersonic flow is required, a convergent-divergent nozzle is required. Otherwise: Conclusion: The Mach number is controlled by the expansion ratio formula_11 Subsonic and transonic wind tunnel Low-speed wind tunnels are used for operations at very low Mach number, with speeds in the test section up
