An adaptation of a primitive variable, finite-difference computer program was made in order to predict the non-reacting flow fields in turbojet test cells. The study compares the predictions of the primitive variable computer model with an earlier stream function-vorticity computer model and empirical data. It was found that the model reasonably predicted the flow fields and allowed simulation of test cell flows up to full engine throttle conditions Prepared for: Naval Air Propulsion Center, Trenton, NJ. http://archive.org/details/primitivevariabl00stev N6237679WR00014

Design considerations were examined for a flow system for transient electrical laser experiments. After a brief review of corona discharge gas flow interaction phenomena, the choice of the size and operating conditions of the discharge cell are discussed. Once those parameters are established, the flow system, which consists essentially of a Ludwieg tube, is designed. Attention is paid to flow starting times, to the available time of steady state flow, and to the effects of the boundary layer on the core flow. Suggested experiments and instrumentation are given in this report Prepared for: Chief of Naval Research, Arlington, VA 22217. http://archive.org/details/designconsiderat00stri N00014 7 9WR90 027 NA

An adaptation of a primitive variable, finite-difference computer program was accomplished in order to predict the reacting flow field in a solid fuel ramjet. The study compares the predictions of the primitive variable computer model with an earlier computer model and empirical data. It was found that the new model reasonably predicted the flow field and permitted calculations within the aft mixing chamber Prepared for: Naval Weapons Center, China Lake, Ca. http://archive.org/details/primitivevariabl00netz N6053079WR30045 NA
