Ua haujlwm cov ntsiab lus ntawm cov zaub mov muab ob npaug rau kauv sib tov

Ua haujlwm cov ntsiab lus ntawm cov zaub mov ua ob chav muab kauv khob ua ke: tus qauv ua haujlwm: Muab ob npaug rau kauv khob khoom sib xyaw yog hom tshiab ntawm cov khoom siv sib xyaw xim. Lub tshuab txais yuav cov txheej txheem ntawm lub cav thiab lub tog raj cycloid tus taw qhia lub ntsej muag kom ua lub kiv puag ncig thiab tig. Siv cov ntsiab cai ntawm kev sib xyaw ua ke ntawm kev sib hloov ntawm cov ntsia hlau ntev thiab luv thiab kev sib hloov ntawm ob lub screws, cov ntaub ntawv nrog cov qauv sib txawv tshwj xeeb sib txawv tuaj yeem mus txog qhov sib xyaw zoo tshaj plaws thiab lub sijhawm sib xyaw. Luv, cov nyhuv zoo. Vim yog lub kiv puag ncig ntawm ob chav helix, cov hmoov ua kom txav mus rau hauv cov lus sib dhos uas yog raws phab ntsa ntawm lub khob hliav qab. Kev sib hloov ntawm cov kauv ntawm lub ntsej muag ua rau cov hmoov paug mus rau hauv nruab nrab ntawm lub khob hliav qab rau kev hloov radial. Cov hmoov no tau tawm los ntawm lub khob hliav mus rau qhov nce siab thiab sab nraud ntawm qhov chaw ntawm lub kauv, uas yog, sib xyaw rau hauv cov kev taw qhia ntawm lub kauv axis. Kev sib xyaw ntawm cov kauv tig thiab kev sib hloov hauv qhov tov ua rau kev txav ntawm hmoov convection, shear, diffusion, thiab infiltration. Yog li ntawd, cov ntaub ntawv tsis sib xws.
