Sentence examples for constant area section from inspiring English sources

In this work, three geometrical factors – the area ratio between the nozzle and constant area section (rA), nozzle exit position (NXP) and constant area section length (Lm) – were considered.

For a given NXP, the system COP and cooling capacity of the steam ejector decreased until inoperative as the diameter of the constant area section reduced.

The effects of the operation temperature, the nozzle exit position (NXP) and the diameter of the constant area section on the working performance of the steam ejector were investigated at generating temperatures ranging from 40 °C to 70 °C.

Lm had little influence on λ; however, longer constant area sections resulted in higher pc,crit.

Results indicate that the efficiency of the ejector decreases with the increase of roughness values and friction losses in constant-area section and diffuser have the most significant impact on ejector performance.

Next, the influence of three geometric parameters such as nozzle exit position, the length of constant-area section and diverging angle of primary nozzle on the ejector performances was investigated via experimental methods.

Three ejectors with a same nozzle for the primary nozzle and three different constant-area sections were designed and fabricated.

Three ejectors with a same de Laval nozzle for the primary nozzle and three different constant-area sections were designed and fabricated.

The optimal ratio of the diameter of constant area mixing section to the steam nozzle throat diameter is about 3.4 and the optimal ratio of length to diameter of constant area mixing section L/Dm is 6.

For this optimum value of flow entrainment ratio w, the value of area ratio At/Ad (cross section of minimum area of primary nozzle/cross section of constant area duct) can be estimated for an ejector's optimum design.

As the HyShot II combustor has a constant-area cross section, the expected behavior in this equivalence-ratio range is the formation and upstream propagation of an unsteady shock train that would eventually lead to inlet unstart.
