Ekwakhiweni kwenqubo yesiqandisi, lapho kucatshangelwa izici zesiqandisi esisebenzayo, ukusebenza kahle komjikelezo wesiqandisi kanye nezimo zemvelo ezingaqinisekile, ukubala kuzoba nzima ukuxazulula, okuyinkinga eguquguqukayo yokusebenza ngaphansi kwezimo ezingaqinisekile ezifundwe kulokhu. iphepha.
Iqembu locwaningo likaProfessor Zhu Lingyu eSikoleni Sobunjiniyela Bamakhemikhali liphakamise isu lokucinga lesifunda legridi elihle eliguquguqukayo ukuze kuseshe isiqandisi esisebenza kahle kakhulu esikwazi ukusebenza ngokuguquguqukayo okukhulu ukuze kuthuthukiswe inqubo kanye nesikhathi sokusebenza kucatshangelwa ukuguquguquka kokusebenza ngaphansi kwezimo ezingaqinisekile.
Inqubo yamakhemikhali ithintwa kalula yizinto ezihlukahlukene ezingaqinisekile ekusebenzeni kwangempela futhi ichezuka esimweni esifanele sokulinganiswa.Lokhu kungaqiniseki ikakhulukazi kuvela ezicini ezintathu :(1) ukungaqiniseki kwamapharamitha wemodeli asetshenziswa ekuklanyweni kwenqubo;(2) ukungaqiniseki kwezici zangaphakathi (njengokushisa nokudluliswa kwe-mass coefficient kanye nezinga lokusabela);(3) Ukungaqiniseki kwezinto zangaphandle zenqubo, njengesimo sokuphakelayo, izinga lokushisa elizungezile nokucindezela, kanye nesidingo semakethe yomkhiqizo.
Ukuguquguquka kokusebenza kwesistimu yenqubo yamakhemikhali kungachazwa indawo engenzeka endaweni engaqinisekile yepharamitha.ESIZINDANENI esinokwenzeka, izidingo zokucaciswa komkhiqizo, umnotho nokuphepha zihlale zaneliswa lapho okuguquguqukayo kokulawula inqubo kulungiswa ngokuthanda kwakhe.Okokuqala, isifunda esinokwenzeka sinqunywa, bese ukuguquguquka kwesistimu yenqubo kuphinde kulinganiswe yisici esiphezulu sokukala ngokusekelwe ku-hyperrectangle yangaphakathi noma inkomba yokuguquguquka esekelwe ku-hypervolume ratio.
Leli phepha lihlongoza isu lokulondoloza kahle ulwazi lokuxhunywa kwegridi kusetshenziswa uhlaka lwedatha yohlu olunezinhlangothi ezimbili, futhi lisebenzisa indlela yesampula yokuphazamiseka okufanayo ukuze kucwengwe futhi kutholwe imingcele yesizinda engenzeka.Ngesikhathi esifanayo, leli su lisekela ukubalwa okuqondile kwe-hypervolume engenzeka ngesamba sama-hypercubes angenzeka kugridi, ngaphandle kokusebenzisa amasu okwakha kabusha umumo.Isu lokucinga legridi elihlongozwayo lingakwazi ukuthwebula umumo oyinkimbinkimbi wesifunda, linciphise izindleko zesampula futhi lingabi nokungahleliwe.
I-Schematic yesu lokusesha igridi enhle eguquguqukayo
Le ndlela isetshenziswe emjikelezweni wefriji yokucindezela umusi wesiteji esisodwa, futhi ukulungiswa kwefriji okusizwa yikhompyutha kwenziwa ukuze kwandiswe ukuguquguquka kokusebenza nokusebenza kahle kwamandla, kanye nokusatshalaliswa kwesiqandisi ngokusekelwe ekuguquguqukeni nasekusebenziseni amandla kahle kwakhethwa.
Isisetshenziswa esiphezulu esivumelana nezimo zomjikelezo wesiqandisi sokuminyanisa isitimu esisodwa
Imiphumela "Yesu lokucinga legridi elicwengekile eliguquguqukayo lokuhlola ukuguquguquka kokusebenza kanye nokusetshenziswa Ekukhetheni kwesiqandisi "yashicilelwa ku-AIChE Journal.Umbhali wokuqala nguJiayuan Wang, Umfundisi eSikoleni Sobunjiniyela Bamakhemikhali, umbhali wesibili nguRobin Smith, uProfesa waseNyuvesi yaseManchester, e-UK, kanye nombhali ohambisana naye uLingyu Zhu, uProfesa weSikole Sobunjiniyela Bamakhemikhali.
Ijenali ye-AIChE ingelinye lamajenali anethonya elikhulu embonini yamakhemikhali yamazwe ngamazwe, ehlanganisa ucwaningo lwezobuchwepheshe olubaluleke kakhulu nolwakamuva ezindaweni eziyinhloko zobunjiniyela bamakhemikhali neminye imikhakha yobunjiniyela ehlobene.
