The exact solutions of the n - s equations are employed to verify the algorithm and the program . the two - dimensional flows past both a still cylinder and a rotating cylinder are computed . our numerical results show good conformance with that from the previous experimental and numerical studies 利用n - s方程的精确解,以及前人研究二维静止圆柱绕流、旋转圆柱绕流等问题的实验和计算结果的比较,对算法和程序作了严格的校验。
Based on detailed analyze on turbine engine and ramjet , a new conceptive internal - rotor burnt rotating ramjet ( irbrr ) with an rotating cylinder in the center of rotor in which the revolved stream can be ram - compressed and burnt has been proposed and some primary research have been done as below : the scheme of structure , principles , thermodynamic cycle and performances of the new conceptive engine has been studied in the paper 本文通过对燃气涡轮发动机和航空冲压发动机的原理结构进行详细分析并进行融合创新,提出了一种利用内置旋转汽缸进行旋转气流冲压压缩和旋流燃烧的新概念内置燃烧室旋转冲压发动机,并进行了一些前期的基础性探索研究,具体研究内容有:对旋转冲压发动机进行了总体方案设计、工作原理分析、气动热力循环和性能分析等概念性研究。
Cylinder dryer is a dind of rotatin continuous drying equipment with internal heating conducting - style , certain thickness of materials film theres to the lower trough of materials under the rotating cylinder . heat is transferred to the internal wall of the cylinder through pipes and misfired ahain to the external wall and to materials film , to evaporate and damnify moisture in materials film so as to dry materials 滚筒干燥机是一种内加热传导型转动连续干燥设备。旋转的滚筒通过其下部料槽,粘附着一厚度的料膜。热量通过管道辅送至滚筒内壁,传导到滚筒外壁,再传导给料膜,使料膜中的湿度得到蒸发、脱湿、使含湿份的物料得到干燥。
On the other hand , the collection on a rotating cylinder is helpful to the process of electrospinning , and it is furthersome to get the ordered mats , otherwise , because the velocity of cylinder rotating is far less than that of nanofiber depositing , the rotation of cylinder has not the function of drawing 另外,采用辊筒收集有利于纺丝工艺的顺利进行,而且辊筒收集能使纤维毡中的纤维较整齐排列,但辊筒的卷绕速度远远小于电纺丝速度,辊筒的旋转不能起到拉伸的作用。
