查询词典 regeneratively

Through the studies on the regeneratively cooled scramjet structure of tomorrows advanced propulsion system of this paper, one thermal evaluation tool was developed. This dissertation provided the necessary means for the design of regenerative cooling channels of the scramjet.

通过本文围绕未来先进推进系统——超燃冲压发动机燃烧室再生冷却结构的研究，发展了热分析计算方法，初步建立了冷却通道的设计方法和工具。

In addition to the regeneratively cooled designs mentioned above, other combustion chamber designs have been fabricated for rocket engines using dump cooling, film cooling, transpiration cooling, ablative liners and radiation cooling.

此外，向再生水冷式的设计，如上所述，其他燃烧室的设计已被捏造为火箭发动机，使用转储冷却，气膜冷却，发汗冷却，烧蚀班轮和辐射冷却。

In order to investigate the basic heat transfer characteristics of the platelet regeneratively cooled thrust chamber, the second chapter focussed on the developed flow and heat transfer in the long straight regenerative cooling channels with rectangular sections.

为了解层板再生冷却推力室在传热上的基本特征，第二章重点研究流动和热充分发展的矩形截面长、直再生冷却通道内的传热问题，建立了层板再生冷却推力室二维流固耦合传热过程的数理模型，采用通用形式控制方程描述冷却剂紊流传热和通道材料内导热的共轭传热问题，从而避免了流-固区域之间的反复迭代，大大缩短了计算时间。

Supercontinuum with an ultra-broad bandwidth of 380 nm to 1750 nm was generated by injecting 250 kHz, 200 fs optical pulses produced from a regeneratively amplified Ti:sapphire laser into a 2.5 m-long polarization-maintaining photonic crystal fiber.
