MODULAR APPARATUS FOR ITERATIVELY EVALUATING COMBUSTION FLOW PROCESS

摘要

A modular apparatus for evaluating flow processes. The apparatus has (i) a closure for a chamber, the closure defining at least one aperture and at least one seating basin facing away from the chamber; and (ii) at least two stacking elements cooperatively associated with each aperture for defining at least one fluid passage communicating with the aperture when stacked on one seating basin, the elements when stacked having mating walls meeting at a parting plane or line along the length of the passage, each element sealingly mating with each other, and one of the elements sealingly mating with the basin. The bottom stacking element snugly seats in and on the basin and defines a surface cooperating with the closure to form a cradle for a top stacking element when placed thereon.
