Mechanics/heat-transfer relation for particulate materials (for July 1991)
The major emphasis this quarter has been in two areas. The first is to continue working the bugs out of the new particle pressure transducer. The second was to try and measure the particle pressures generated in a bed catalyst that is undergoing particulate fluidization. The results indicate that the stabilization of fluidized beds in that regime cannot be explained in terms of particle pressure generation. Instead, consistent with other recent observations, the observations can be explained by a material is that not completely fluidized but, instead, retains much of the properties of a solid and, in particular, can transmit particle pressure like a solid. Also, in this quarter, one of the author's students, David Wang, successfully defended his PhD thesis; his research was sponsored by this grant and concerned both the thermal conductivity measurements and the early work on particle pressures in fluidized beds. The particle pressure work was also presented at the ITEM Symposium on the Mechanics of Fluidized Beds, held at Stanford in the early part of this month.
