A "mini-thread" on the evaporation of water drops

Summary

This thread will have a mix of NACA-era and post-NACA era data on water drop evaporation.

Topics:

Irving Langmuir, "Super-Cooled Water Droplets in Rising Currents of Cold Saturated Air"

Evaporation and condensation rates on water drops are calculated.

Let's build a 1D particle motion simulation: Impingement on the stagnation point of a cylinder

A 1D water drop motion simulation is built.

The AEDC 1-Dimensional Multi-Phase code (AEDC1DMP) and the iads1dmp

Water drop evaporation rates in an icing tunnel are calculated.

NACA-TN-3024 revisited

Less that 1% of drops evaporate approaching an obstacle for most cases.

The next thread in the NACA review series is the Icing Wind Tunnel Test Thread.
