-
Freezing efficiency of f atom in oxidant nozzle of different contour walls, mixing mechanism of reactants in 2slot ( two - dimensional, plane symmetry nozzle ) nozzle and comparison of flow - fields & ssg between 2slot and 3slot ( 3 - slit jet plane nozzle ) have been studied by using 2d cr program. the conclusion is significant to understand the requirement of reactant flows and to generate ideas for nozzles design
利用二維r程序，研究了單噴管型面對f原子凍結效率等參數的影響：研究了二維平面對稱噴管（ 2slo ）的反應流混合機制和混合角對激光器性能的影響；對比研究了zslot和三狹縫平面對稱噴管oslot ）流場和增益特徵。 -
These measures are as follows : shorten the primary wind intervals to improve thermal load of the burner ; reduce the size of hypothetical circle of contact to prevent the flame from splashing ; use nozzles with larger height / width ratio to increase the effusive rigidity, so as to increase the jet flow depth of secondary wind into the main jet flow ; use a higher primary wind velocity to increase its jet flow rigidity ; use a special flame holder structure of the primary nozzle, so as to improve
這些技術措施主要有:縮小一次風間距以提高燃燒器區域熱負荷;縮小假想切圓防止火焰刷墻;採用高寬比較大的二次風噴口以增加射流剛性，提高二次風射流進入主射流的深度;採用較高的一次風速來提高一次風射流剛性;一次風噴口採用特殊穩燃結構;提高下二次風的托粉能力。 -
