Computational fluid dynamics (CFD) yog ib qho kev tshawb fawb uas siv cov qauv ntaub ntawv los daws cov teeb meem ntawm cov dej ntws - xws li kev tshaj tawm, qhov ceev, thiab cov tshuaj lom neeg. Cov thev naus laus zis no yog siv rau hauv thaj chaw xws li kev tiv thaiv cavitation, kev tsim hluav taws xob aerospace, HVAC engineering, kev tsim hluav taws xob, thiab ntau dua
Vim li cas peb thiaj siv cov kua dej sib xyaw ua ke?
Computation fluid dynamics (CFD) yog ib qho engineering cuab yeej siv los simulate qhov kev txiav txim ntawm thermo-kua nyob rau hauv ib qho system Nws yog siv los ntawm ntau lub lag luam hauv lawv txoj haujlwm txhim kho los tshuaj xyuas, optimize thiab txheeb xyuas qhov kev ua tau zoo ntawm cov qauv tsim ua ntej tus qauv tsim thiab kev sim lub cev.
Daim ntawv thov ntawm CFD yog dab tsi?
Ntau qhov chaw ntawm CFD daim ntawv thov suav nrog architecture, tshuaj thiab txheej txheem engineering, electronics thiab computer, HVAC (kub, cua & cua txias), roj av, tsheb ciav hlau tsim, turbo machinery thiab lwm yam Nws lub cev Cov ntawv thov suav nrog cov hlab plawv (Lub plawv, cov hlab ntsha loj), ntws hauv ntsws thiab ua pa.
Kev siv CFD yog dab tsi?
Qee qhov kev lag luam tseem ceeb uas CFD simulation nquag siv yog Aerospace / Aeronautics, Automotive lossis Tsheb, Tsev HVAC [(cua sov, cua sov, thiab cua txias), Tshuaj / Petrochemicals, Zog / Fais Fab Tsim, Tsim / Txheej Txheem Engineering, roj thiab roj kev lag luam, Khoom tsim thiab …
CFD siv li cas hauv aerospace?
CFD yog siv thoob plaws hauv cov txheej txheem tsim, los ntawm kev xav-rau-ntaub ntawv, kom qhia txog cov ntsiab lus pib thiab kho cov ntsiab lus siab heev … CFD yog siv los kwv yees tus luag, nqa, suab nrov, structural thiab thermal loads, combustion., thiab lwm yam., kev ua tau zoo hauv aircraft tshuab thiab subsystems.
