FLOW PROCESSES IN NOZZLES

Zadatak završnog rada bio je obraditi temu strujanja u mlaznicama. U završnom radu su opisani osnovni tipovi strujanja fluida te njihove karakteristike. TakoĎer definiraju se jednadţbe vezane za strujanje fluida kroz cijev i mlaznicu koje se kasnije koriste u izradi proračuna. Opisani su različiti oblici strujanja kroz mlaznice. Analiziraju se oblici mlaznica te specifičnosti vezane uz de Lavalovu mlaznicu. Rad obuhvaća i proračun za dvije vrste plina koji struje kroz mlaznicu s različitim ulaznim brzinama. Na kraju rada usporeĎeni su dobiveni rezultati pomoću stupčastih dijagrama.Purpose of the final paper was to elaborate the topic of flow in nozzles. Main types of fluid flows have been described in the final paper, as well as their characteristics. In addition, all equations related to fluid flows through the tube and nozzle which are used in calculations have been defined. Different types of flowing through the nozzles have been described. The shapes of nozzles and their specifications related to the de Laval's nozzle have been also analyzed. The paper includes calculation for two different types of gases which flow through the nozzle with different inlet velocities. The results obtained in the paper are compared at the end of the paper using bar diagrams
