Newtonian Urume chacho antipode - chii?

Newtonian uye non-Newtonian zvinwiwa mumakore achangopfuura kukonzera vafarire kwete chete nyanzvi asiwo vanhuwo. Izvi imhaka yokuti Non-Newtonian Zvinoyerera iri nyore nemaoko avo pachavo uye zvakakodzera musha Zara. Chokutanga patichanzwisisa, kuti kazhinji kuti vakadaro zvinhu. Newtonian Urume rinoteerera Newton kwakaita viscous kukweshera, uye saka akawana zita rayo. Maererano nomutemo uyu, ari fura kunetseka iri ndege yacho kuonana akaturikidzana ndiyo Proportional kuti rinobva emura kubva ayo nokubuda velocity nenzira zvakajairika ndege iyi zvakananga.

Rinonzwika tsvarakadenga yakaoma, asi muverengi achava kunzwisiswa zviri nani, kana tinoti Newtonian mvura - mvura, mafuta uye vakawanda yaizivikanwa kwatiri kushandisa zuva nezuva zvinwiwa, kureva vaya vanochengeta muviri wavo wakadini, kuti chero chaunoita navo ( asi nyaya kwemvura kana kuoma nechando, chokwadi). Asi kana ukama zvinorondedzerwa tsananguro kumusoro inversely Proportional kuti, tinogona kutaura non-Newtonian mvura.

mvura yakadaro nguva dzose homogeneous, ine mamorekuru huru kuungana munzvimbo lattices, saka viscosity kunoenderana kuerera mwero mukomboni. The yepamusoro nokukurumidza, dzakanga dziri viscosity. Neimwe hworudzi urwu yeimwe zvinosanganisira thixotropic mvura, kureva, avo kuti kushandura viscosity pamusoro nguva, somuenzaniso, richizadza kana chokoreti. Uyewo, mamwe masayendisiti kuti vanodavira ropa pfuma haaiti maererano nemitemo Newton aiva viscous kukweshera, nokuti non-dzakafanana mvura, ndiko kumisa zviri yeplasma uye zvakasiyana-siyana emasero ropa. chiremba Chero achasimbisa kuti viscosity ropa dzinosiyana munzvimbo dzakasiyana-siyana kweropa ino, izvo kazhinji zvokurwara. Zvisinei, kwete fuma yose iri musimboti anokwanisa ane metamorphosis akadaro.

Non-Newtonian mvura inogona kugadzirwa pamba chaizvo nyore. Tinofanira kutora 1.5 zvikamu starch (Zvakanakisa zviyo, mbatatisi asi iyewo achaita) uye chikamu mvura chete. Zvokubikisa zvinofanira kusanganiswa zvishoma nezvishoma kuitira kudzivisa nemavhinga. Zvakanakisa, inofanira ugovere kumbonyanya dzakaonda rukoko pamusoro kubika jira, asi chokwadi, unogona kuona chero kudyidzana. Edza kukurumidza "acheter" emura minwe, uye zvichava kutarisa uye sokuti nechando guru epurasitiki. Sununguka minwe yako - uye nemvura iri vakapedzwa. Newtonian fluid mazano akadaro havakwanisi! Unogona dhayira rimwe fuma iri tsama ezvokunwa kutanga naro. Nokukurumidza, uchava namuka uye mapurasitiki, uye naizvozvo kana zaplyashet mumaoko enyu - ndiwo chinofadza zvikuru kuona! Isa akakwidza mvura kuva bhora, ndizvo kwakavharwa nenyama uye inofadza, uye zvakafanira kuzorora ruoko - vachaparadzirwa kwose. Zvinofadza kuti kuwedzera nayo madhayi kutamba nevana. Vamwe enda mberi uye edza kuti kunyange kumhanya pamusoro asiri Newtonian fluid rwakapetwa pamusoro payo uye nezvimwe zvinhu, asi kuedza kwakadaro, Chokwadi, vanoda zvinhu zvakawanda kupfuura kumba Zara. Unogona kuwana zvakawanda mavhidhiyo maripoti uye kuramba kuongorora hunonakidza nyika wefizikisi.
