Program Goals

Both projects are at the level of basic research. Goal for 1 is to improve wind turbine performance. Goal for 2 is to better understand droplet formation in clouds . The effects of clouds on climate change are less well understood than are all of the other components of the atmosphere.

Brief Description

The work involves wind tunnel experiments. For topic 1, complex wind fields are created in a wind tunnel and attempts to relate these to real atmospheric situations are made (see reference 1). For topic 2, water droplets are sprayed into highly turbulent flows. Effects of droplet clustering, entrainment and boundary layers are studied (reference 2).
