OpenFOAM: Vhura Sosi yeComputational Fluid Dynamics

OpenFOAM Ndicho Bhokisi rekushandisa (ToolBox) na Open Source uye inogadzirisika, inoshandiswa mu Computational Fluid Dynamics (Computational Fluid Dynamics - CFD).

Kunze kwekuvhurika, iri zvakare vakasununguka uye inogadzirwa ne OpenFOAM Nheyo. Uye inogoverwa chete pasi peiyo General Ruzhinji License (GPL), kubatsira vanhu vese.

OpenFOAM yasarudza iyo GPL Rezinesi kupa vashandisi vechirongwa, iyo rusununguko rwekugadzirisa uye kugovera patsva software uye garandi yekuenderera kwekushandisa kwemahara, mukati memitemo yelayisensi. Kugadzira zvakafanana, a yakanakisa imwe nzira mundima iyi inopesana nekambani, dzakavharwa uye dzekutengesa mhinduro.

Izvo zvakakosha kuti uzive izvo OpenFOAM yakasikwa uye yakaburitswa nemugari Henry weller, mugore 1989, pasi pezita re "FOAM»Uye yakaburitswa sa«OpenFOAM"by Henry Weller, Chris Greenshields naMattijs Janssens, muna Zvita 2004. Kubva ipapo, OpenFOAM yakaramba ichitarisirwa uye kuvandudzwa neshanduro nyowani dzinoburitswa kuruzhinji gore rega rega. Uye yazvino vhezheni yakagadzika yakaburitswa nhamba 7.

OpenFOAM: Vhura ToolBox yeCFDs

Chii chinonzi Computational Fluid Dynamics?

Maererano ne ESSS blog, webhusaiti yakasarudzika mune iyi nyaya, mune izvi chinyorwa, Ichi chi:

"Computational Fluid Dynamics kana CFD (Computational Fluid Dynamics) inzvimbo yeruzivo iyo inobata nekuenzanisa kwekuverengera kwekuyerera kwemvura, kupisa kupisa uye zviitiko zvinoenderana zvakadai sekushanduka kwemakemikari, kupisa, aeroacoustics, nezvimwe. Iyo CFD yakatanga kubva mukubatanidzwa kwedzidziso mbiri: fluid fluid uye kuverenga kuverenga. Ma equation anotonga kuyerera kwemvura ane mavambo awo mune fluid mechanics uye anogona kugadziriswa nenzira dzakasiyana dzenhamba nzira".

"Computational Fluid Dynamics inoshandiswa zvakanyanya muzvikamu zvakasiyana zveindasitiri uye inotsigira dhizaini nekugadzirwa kwemazana ezvigadzirwa, sendege, mota nezvikepe, pamwe nemhando dzakasiyana siyana dzemidziyo yemumaindasitiri. Computational Fluid Mechanics inogona kushandiswa kubva padanho rekufungidzira reprojekti, ichibatsira kuona kugona uye mhinduro yechigadzirwa, kusvika padanho rekugadzira, ichibvumidza kumiririra zviitiko zvakasiyana".

Ndeapi maficha ane OpenFOAM?

OpenFOAM ine yakafara huwandu hwezvinhu. Pakati peizvi tinogona kutaura:

Iko kugona kuteedzera chero chinhu chakanangana nenzvimbo yeCFD, senge: Kutenderera kunoyerera mumotokari aerodynamics, kusvika pamoto uye kudzima moto muzvivakwa, zvinosanganisira kupisa, makemikari maitiro, kupisa kupisa, mvura inosasa uye mafirimu.
Inosanganisira maturusi ekupinda mukati uye kutenderera akaomarara ejometri (semuenzaniso, mota), uye yekugadzirisa data uye kuona, pakati pevamwe.
Mhanya zvakaenzana kuverenga seyakajairwa kutora mukana uzere wemanhasi-epakati processor uye makomputa-akawanda emakomputa.

OpenFOAM inogona kupi kuwanikwa?

Iyo yepamutemo webhusaiti ye OpenFOAM Icho chiri muChirungu asi chine inonzwisisika uye iri nyore kuongorora interface. Iyo zvakare ine mamwe masayiti ekubatsira ane ruzivo rwakawanda. Zvino zvakafanana:
