Nguva yemvura

Kana ukamira panzvimbo inotarisa kuchamhembe kwenyika muzhizha, unogona kuzviona nenzeve dzako: mazuva ese, madziro emvura anosvika uye anoparadza. Mahombekombe anogadzirwa nemhepo inofamba makiromita akawanda mumvura yakavhurika, saka ndeimwe nzira yekuvaka simba remhepo. Vachiramba vachisvika mushure mekubuda kwemhepo, nezuva sezvavanoita nenguva yezuva, uye zvikuru muzhizha, panguva iyo mapaneli ezuva anogadzira simba rakawanda.

(Ichi ndicho) chikumbiro chechokwadi. Iyi peji, yakanyorwa nechokwadi chakafanana nechero Fan Wall research yedu, inotsanangura kuti nei paive zvakaoma kutevedzera chibvumirano ichi. The short version: ** physics mabasa uye chiwanikwa ndechikuru, asi wave machine anofanira kupora zvekare mahombekombe apo kurarama masikati ano kuti vatore makumi maviri nguva kupfuura simba. Pashure pechiuru chemakore uye makambani akawanda akakundikana, simba remvura rinogara riine mutengo wakakwira kupfuura simba rezuva, pasina kubudirira kwesainzi. Inogona kukunda pakutanga apo simba rine mutengo wakakwira uye mvura yemusango ndiyo chete inosangana nayo.**

Chii icho

A wave simba converter ndeimwe michina iyo inoshandura kutenderera kwemvura kuita magetsi. Zvisiri zvazviri nemhepo, apo imwe dhizaini (iyo matatu-bladed turbine) yakakunda, simba remvura rine mazana ezvipikirwa zvinokwikwidza. Vanobva vapinda mumhuri dzakawanda:

• Point absorbers: mabhureki anotambanudza pamusoro pemvura uye anobata anchor kana chikepe chinorema. CorPower’s C4 ndiyo imwe.
• Attenuators: refu, snake-senge mabhawa ari kugara pamwe chete nechinangwa chemahombekombe, bending pazvifukidziro. Pelamis aiva muenzaniso wakanaka.
• Oscillating wave surge converters: zvigunwe zvehusiku pamadziro ekunze anenge akatarisana negungwa izvo zvinofamba-famba. Aquamarine Power’s Oyster yaive imwe.
• Oscillating water columns: mabhodhoro anovhurwa kumvura pasi pechidzitiro chemvura. Mahombekombe anosimudza madziva mukati memvura kusvika pamusoro uye pasi, izvo zvinomanikidza mhepo kubuda nekuenda kunze kuburikidza neturbine. Mutriku muSpain ine makumi maviri nemana ezvivakwa zvakaiswa muvharo wehotera.
• Overtopping michina: ramps kuti vaite mabwe kubuda muzvibereko, uye wobva waisa madziro pamusoro low-head turbines.

Maitiro ekushanda

Energy in a wave. A wave’s energy is stored partly as water lifted above the average sea level and partly as the water’s motion. Panzvimbo peiyo yakaoma mvura yekunze, iyo inoratidzwa neyakajairika wave height H (inofungidzirwa kuti ndiyo yakakura kupfuura imwe threeth yemadziro), simba rezuva rinobva pamita imwe chete yemvura yekunze iri E = ρ g H² / 16, apo ρ ndiro density yemvura yekunze uye g gravity. Kuwedzera kukwira kwemvura kunowedzera simba.

Power, the number that matters. Wave energy travels, at the group speed g T / 4π in deep water, where T is the wave period. Kuwedzera simba nesimba uye simba richisvika pamwechete neimwe mita yewave front i P = ρ g² H² T / 64π, iyo inoshanda se anenge 0.49 × H² × T kilowatts per metre. A 2.5 m sea ne9 s nguva inotakura pamusoro 28 kW pasi pamwechete neimwe meter of coast: kupfuura gore, simba rezviuru zvemaguta per metre, kana zvese izvi zvinogona kuwanikwa. The explainer pamusoro inokutendera iwe kuedza dzimwe mvura.

Zvinoita madziro. Mumvura yakadzika, madziro ari mumvura haasi kufamba nemvura: zvose zvinofamba mumigwagwa uye zvinodzokera kwazvakatanga. Makumbo anodonha nekukurumidza nekumhanya; panguva yechiedza ichi chiri pasi pewavelength, kutenderera kunosvika 4% chete kwechiedza chinopinda muvhu. Mahombekombe emvura yakadzika mahombekombe akareba: wavelength ndeye 1.56 × T² metres, saka 9 s wave iri 126 m kubva kumusoro kusvika pasi. Izvi ndizvo zvinoita kuti simba remvura rive pedyo nenzvimbo yepasi uye kuti zvigayo izvi zvirege kutambanudza kana kugara mumvura yakapfava.

Kusvibisa mvura, ita mvura. Mashini emvura anotora simba nekufamba nenzira iyo inobvisa chikamu chemvura iri kuuya. Kuti uwane mvura inofamba-famba, iyo inofamba chete kumusoro uye pasi, izvi zvinopa huwandu hwakanaka: zvisinei kuti ndeipi simba richasvika pamusoro pekureba kwechikepe, hachisi chinhu chinoita kuti chikepe chirege kukwira kana kushumira. λ / 2π, imwe wavelength yakavakirwa pa2π, pamusoro pe20 m ye9 s wave (Falnes, 2002). Kusvikawo kuti inofanira kuchinja buoy’s motion kuti arambe munzira nemvura, izvo ndezvekuti sei control systems iyo inodzora machine kune imwe neimwe wave ichienda zvinhu zvikuru. In practice, measured and modelled machines capture typically between a tenth and a third of the power arriving across their own width (Babarit, 2015).

Slow, huge forces. Muviri wemvura unomanikidza nesimba guru asi unofamba zvakaomarara, mita imwe kana mbiri pamasekondi mashoma. Generators vanoda nyore, nyoro kutenderera, saka chero wave muchina inofanira power take-off kuti anoshandura imwe kune imwe: hydraulic rams uye mabhatiri, air turbines, direct-drive linear generators kana mechanical gearboxes. Muchidimbu, pfungwa yekuti zvinhu zviviri izvi zvinoda kusangana.

Mitemo: Theoretical uye Practical

Chimwe chinhu. Panguva imwecheteyo, 2.1 TW yemagetsi emvura anosvika kumahombekombe epasi rose, ayo ari pamusoro pe3.4 TW (Gunn uye Stock-Williams, 2012). Kunyangwe zvikamu zvishoma chete zvinokwanisa kuitwa: michina haigone kutevedzera chero pedyo negungwa, simba rinorasikirwa sezvamahombekombe anosvika kumahombekombe, uye zvakawanda zvemari idzi zviri mumamiriro ekunze akaomarara emahombekombe ekumadokero. Kuchamhembe kweAmerica kunosangana nemhepo dzekumadokero pakati pe40 uye 60 degrees of latitude: Ireland, Scotland, Portugal, Chile, Australia yekumaodzanyemba, New Zealand, Pacific Northwest yeUnited States. Mahombekombe akavharwa seMediterranean anowana chete mamwe makilowatts pamita.

The storm problem. The explainer’s storm button makes the central difficulty visible. A machine yakagadzirwa kuti iite mari yake mumvura ye1 kusvika 4 m, asi inofanira kurarama mumvura ye10 kusvika 15 m, ichitakura makumi maviri nemaviri kana kupfuura nguva dzesimba, uye imwe mabwe akakura kupfuura. Kugadzira chivakwa chekupisa kwezuva kunoita kuti zvive zvakaoma uye zvinodhura; kugadzirira kwayo kwemvura inopisa inoita kuti zvive zvisina kusimba. Zvimwe zvivakwa zvemagetsi zvinopa simba iri nekushandisa mhepo. A wave machine haazombobuda mumvura.

Fatigue. Nenguva ye8 masekondi, muchina unosangana nemazana mana ezviuru zvemadziro pagore, ese ari maviri achikanda, achimanikidza uye achipinza ma joints ayo, zvisimbiso uye ma moorings. Panguva yemakore makumi maviri, izvo zvinoreva kuti pane zviuru mazana matanhatu zvemabasa emvura yakasviba.

Kusvika uye kutakura. Sezvaanoda zvese zvemagetsi zvemvura, mabhawa emagetsi anogona kuiswa chete uye kugadziriswa munguva yekunze yakachena, uye ivo vanogara zvakajeka uko nguva yekunze iri yakanyanya kusimba. Kugara kwechikepe mumvura ichiita mhepo kunofanira kutevedzera chimiro chinofamba pasina kusvibiswa kana kudhonza.
