ABSTRACT:
Apparatus for evaluating the characteristics of mixed fluids while under a static or "stopped-flow" condition. Fluid injector pistons force the fluids to be mixed into a mixing chamber, and from the mixing chamber the fluids enter an evaluation or test cell. An amount of mixed fluid in excess of that required to occupy the evaluation cell is introduced into the cell with the excess fluid being exhausted from the cell into an accumulator which maintains a pressurized fluid state. The evaluation cell includes quartz windows permitting light to pass through the cell after flow of the mixed fluid ceases after termination of the fluid injection, and the evaluation cell may also include electrodes to permit both light transmitting characteristics and electrical characteristics of the mixed fluid to be tested. The subsequent cycle of operation purges the cell of the previously mixed fluid permitting a fresh mixture to be introduced into the cell for testing and evaluation. Injection of the fluids into the mixing chamber may be produced with a combination electrical-mechanical drive mechanism, or may be produced by a pressurized fluid, such as compressed air.
