Kunzwisisa Kuyerera: A Comprehensive Guide
Kuyerera ipfungwa yakakosha mufizikisi neinjiniya, zvichireva kufamba kwemvura (mvura kana gasi) kubva panzvimbo kuenda kune imwe. Iyo yakakosha paramende mumashandisirwo mazhinji, kubva kumaindasitiri maitiro uye masisitimu ekutonga mvura kune zvakasikwa ecosystem uye kunyangwe mumiviri yedu pachedu. Ichi chinyorwa chinopa kutarisa kwakadzama kuti kuyerera chii, marudzi akasiyana ekuyerera, kuyerwa kwaanoitwa, uye mashandisirwo ayo munzvimbo dzakasiyana siyana.
Chii chinonzi Flow
Kuyerera kunotsanangurwa sekufamba kwezvimedu zvemvura mukati mepakati. Mhando dzekutanga dzezvinwiwa zvinwiwa uye magasi. Kuyerera kunogona kutsanangurwa maererano nevelocity, kudzvanywa, uye gwara. Chidzidzo chekuyerera chinosanganisira kunzwisisa maitiro ezvinwiwa pasi pemamiriro akasiyana uye mabatiro aanoita nenzvimbo dzawo.
Mhando dzeKuyerera
Kuyerera kunogona kuiswa mumhando dzinoverengeka zvichienderana nemaitiro akasiyana-siyana, akadai sechimiro chekufamba kwemvura, hurongwa hwekuyerera, uye zvimiro zvemvura. Heano marudzi makuru ekuyerera:
Laminar Flow
Laminar inoyerera inoitika kana mvura inoyerera muzvikamu zvakaenzanirana, pasina kukanganisa pakati pavo. Rudzi urwu rwekuyerera runoratidzwa nekufamba kwakatsetseka uye kurongeka kwemvura. Velocity yemvura inoramba iripo chero ipi zvayo mundima yekuyerera. Laminar kuyerera kunowanzo kucherechedzwa kune yakaderera kuyerera velocities uye mumvura ine yakakwira viscosity.
Kuyerera Kwenyonganyonga
Turbulent flow inoratidzirwa nechaotic uye irregular fluid kufamba. Murudzi urwu rwekuyerera, zvimedu zvemvura zvinofamba nenzira isina kujairika, zvichikonzera kusanganiswa uye kuchinjika kwevelocity nekumanikidza.
Turbulent flow inowanzoitika pahigh flow velocities uye mumvura ine low viscosity. Inowanzoonekwa muzviitiko zvechisikigo zvakadai semvura inoyerera uye mamhepo emhepo.
Transitional Flow
Transitional flow inzvimbo yepakati pakati pelaminar uye turbulent flow. Izvo zvinoitika kana kuyerera kwevelocity kwakakwira zvakakwana kukanganisa kuyerera kwelaminar asi isingakwani kuchengetedza mhirizhonga yakazara. Kuyerera kwekuchinja kunowanzoonekwa mukuyerera kwepombi uye miganhu yemiganhu.
Compressible uye Incompressible Flow
Compressible kuyerera kunoitika kana density yemvura inochinja zvakanyanya nekumanikidza. Rudzi urwu rwekuyerera rwakajairwa mumagasi, kunyanya pamasevhisi akakwira uye pasi pemamiriro ekumanikidzwa akasiyana. Incompressible kuyerera, kune rumwe rutivi, inotora kuti mvura yakawanda inoramba iripo. Iyi fungidziro inowanzoshanda kune zvinwiwa uye yakaderera-velocity gasi inoyerera.
Kuyerera Kwakadzikama uye Kusina Kutsiga
Kuyerera kwakadzikama kunoreva kuti mafambiro ekuyerera (velocity, pressure, uye density) haashanduke nenguva chero ipi zvayo mumvura. Kusiyana neizvi, kuyerera kusina kusimba kunoitika kana maparamita aya achisiyana nenguva.
Kuyerera Kuyerera
Kuyera kuyerera kwakakosha mumashandisirwo akasiyana siyana kuve nechokwadi chekushanda, kuchengetedzeka, uye kutonga
kutevedzera. Chiyero chekuyerera chinosanganisira kuona huwandu hwemvura inopfuura nepanzvimbo panguva yakapihwa. Kune nzira dzakasiyana uye zvishandiso zvekuyera kuyerera, imwe neimwe yakakodzera kune chaiwo marudzi emvura uye kuyerera mamiriro.
Kuyerera Kuyera Nzira
Volumetric Flow Rate
Volumetric flow rate ihuwandu hwemvura inopfuura nepapoindi panguva yeyuniti. Inowanzoyerwa mumacubic metres pasekondi (m³/s) kana marita paminiti (L/min). Zvishandiso zvakaita sema rotameters, turbine flow meters, uye positive displacement metres zvinowanzo shandiswa kuyera volumetric flow rate.
Misa Flow Rate
Misa yekuyerera huwandu hwemvura inopfuura nepapoindi panguva yeyuniti. Inowanzo kuyerwa makirogiramu pasekondi (kg/s) kana mapaundi paawa (lb/h). Coriolis kuyerera kwemamita uye thermal mass flow met mita anowanzo shandiswa kuyera huwandu hwekuyerera.
Velocity Flow Rate
Velocity flow rate inoyera kukurumidza kuri kufamba zvimedu zvemvura. Inowanzopimwa mumamita pasekondi (m/s). Zvishandiso zvakaita semachubhu epitot, ultrasonic kuyerera mita, uye electromagnetic kuyerera kwemamita anogona kushandiswa kuyera kuyerera kwevelocity.
