B編}, month = {}, note = {The theoretical calculation of a two-stage high-velocity oxy-fuel thermal spray gun was conducted for the purpose of predicting the stagnant pressure in the mixing chamber (MC). The theoretical results were compared with the experimental ones obtained by the cold flow and actual spray gun tests. The effect of the diffuser shape installed between the combustion chamber (CC) and the MC was also investigated in the cold flow test. It was clarified in this study that 1) the theoretical calculation shows that in order to obtain a larger pressure in the MC the diameter rations of d3t/d1t and d1e/d1t should be chosen to satisfy Eq.(11), to keep the diffuser throat unchoked, 2) the theoretical results of p03/p01 agree with the results of cold flow test within an accuracy of 6%, 3) the theoretical results of p01 agree with the results of actual two-stage HVOF gun test within an accuracy of 4%, demonstrating the validity of the present theoretical calculation.}, pages = {86--95}, title = {超音速流を用いる2段高速フレーム溶射ガン内の圧力特性に関する理論解析 : コールドフロー試験と実機試験による検証}, volume = {77}, year = {2011}, yomi = {カタノダ, ヒロシ and モリタ, ヒロミツ and キリアキ, タクロウ and ヤマノクチ, リサ and カワキタ, ジン and コマツ, マサユキ and クロダ, セイジ and フクハラ, ミノル} }
