and thermocouples reveal the effect of an electric field on the
flow around a stationary, idealized turbine blade downstream of
a combustor. The hot products of combustion naturally include
positive ions. When the blade is an electrode and elevated to a
positive potential, it tends to attract the free electrons and
repel the positive ions. Due to their lower mass, the light
electrons are rapi
