This report describes the research performed during the
period July 1990-July 1991 under a joint research
program between the Mechanical Engineering Department of
the University of Maryland and the Building and Fire
Research Laboratory of the National Institute of
Standards and Technology. The research is conducted by
Graduate Research Assistants of the ME Department under
the joint supervision of Dr. di Marzo (UMCP) and of Dr.
Evans (CFR - NIST). This joint research program was
initiated in January 1985. The long term objective of
the study of droplet-solid interaction is to obtain
information applicable to the extinguishment of fire
through a droplet array (e.g. spray). The solids of
concern include low thermal conductivity materials,
typical of fire applications. Several important results
were obtained in the first years of research. In
particular, the modelling of the boundary condition at
the liquid-vapor interface (at the droplet exposed
surface) was validated with the data collected for water
droplets evaporating on an aluminum block (diMarzo
1986a, 1986b, 1988).
