Test-Model-Induced Interference Effects in Expansion Tube Flows

A New Model for Prediction of Heat Eddy Diffusivity in Pipe Expansion Turbulent Flows

A new model to calculate heat eddy diffusivity in separating and reattaching flows based on modification of constant Prt is proposed. This modification is made using an empirical correlation between maximum Nusselt number and entrance Reynolds number. The model includes both the simplicity of Prt=0.9 assumption and the accuracy of two-equation heat-transfer models. Furthermore, an appropriate l...

Cortactin in the Test Tube

stress fibers, do not contain cortactin. Despite the substantial size of the cortactin literature (currently the word “cortactin” appears in 339 articles), the most fundamental questions are still open. Thus, although cortactin has been implicated in the above-mentioned processes, its exact role is still not clearly defined. Its obvious participation in many of these fundamental events together...

Test-Tube Baby

A test-tube baby [4] is the product of a successful human reproduction that results from methods beyond sexual intercourse [5] between a man and a woman and instead utilizes medical intervention that manipulates both the egg [6] and sperm [7] cells for successful fertilization [8]. The term was originally used to refer to the babies born from the earliest applications of artificial insemination...

The Isentropic Compression Tube: a New Approach to Generating Hypervelocity Test Flows with Low Dissociation

A new approach to generating high-velocity air flows with very low ambient dissociation levels is discussed. Briefly, the approach utilizes a nonsteady isentropic compression wave which is focused through an area contraction to accelerate and compress the test gas. This processed gas may be used directly as a test medium or may be allowed to expand nonsteadily through the expansion wave which a...
