Description
Inrichting voor het opwekken van energie door gebruik te maken van een stromend fluïdumDevice for generating energy by using a flowing fluid
Deze uitvinding heeft betrekking op een inrichting voor het opwekken van energie door gebruik te maken van een stromend fluïdum. Hierbij denkt men al gauw aan windenergie en S ook dat de hoeveelheid opgewekte energie uitsluitend afhangt van de windsnelheid oftewel de stroomsnelheid van de luchtdeeltjes. Dit is niet helemaal waar, want deze opgewekte energie is ook afhankelijk van de massa van de luchtdeeltjes en de hoeveelheid luchtdeeltjes, die per tijdseenheid tegen de schoepen of wieken van de windmolen aanbotst.This invention relates to a device for generating energy by using a flowing fluid. In this context, it is soon thought that wind energy and S also mean that the amount of energy generated depends solely on the wind speed, or the flow speed of the air particles. This is not entirely true, because this generated energy also depends on the mass of the air particles and the amount of air particles that collide with the vanes or blades of the windmill per unit of time.
In plaats van stromende lucht, zou men ook stromend water in rivieren kunnen gebruiken, 10 waarbij simpelweg de molen ondersteboven in het water wordt gedompeld. Alhoewel de stroomsnelheid van het water 10 tot 100 keer zo laag is, en de massa van de waterdeeltjes ongeveer anderhalf keer zo laag, is het aantal deeltjes per volume-eenheid ongeveer 1500 keer zo hoog. Dat betekent dat de hoeveelheid opgewekte energie met een zogenaamde watermolen minstens 10 keer zoveel bedraagt als bij een windmolen.Instead of flowing air, one could also use running water in rivers, simply dipping the mill upside down in the water. Although the flow rate of the water is 10 to 100 times lower, and the mass of the water particles approximately one and a half times lower, the number of particles per unit volume is approximately 1500 times higher. This means that the amount of energy generated with a so-called water mill is at least 10 times as much as with a windmill.
15 Een heel groot voordeel van de watermolen ten opzichte van de windmolen, is dat er minder heftige fluctuaties in de hoeveelheid opgewekte energie optreden, omdat de stroomsnelheden van de waterdeeltjes niet zoveel schommelen als de stroomsnelheden van de luchtdeeltjes. In sommige gevallen levert de windmolen helemaal geen energie omdat het te zacht of te hard waait. Dit in tegenstelling tot de watermolen, die continu 24 uur per dag energie levert.A very big advantage of the watermill compared to the windmill is that there are less violent fluctuations in the amount of energy generated, because the flow velocities of the water particles do not fluctuate as much as the flow velocities of the air particles. In some cases the windmill does not provide any energy at all because it is too soft or too strong. This is in contrast to the water mill, which continuously supplies energy 24 hours a day.
20 Een groot nadeel van de watermolen is dat er planten en dieren met de stroming van het water meegevoerd worden, die in aanraking met de watermolen er niet ongeschonden vanaf zullen komen. Ook zal met de stroming allerlei soorten afval meegevoerd worden, die de schoepen van de watermolen kunnen beschadigen.A major drawback of the water mill is that plants and animals are carried along with the flow of the water, which will not come out intact in contact with the water mill. All kinds of waste will also be carried along with the flow, which can damage the blades of the water mill.
Dat zijn waarschijnlijk de redenen waarom de watermolen momenteel niet gebruikt wordt 25 voor energieopwekking.These are probably the reasons why the water mill is currently not used for energy generation.
Toch is er een manier om energie uit stromend water te halen zonder de nadelige gevolgen van een watermolen en met de genoemde voordelen van een watermolen. Namelijk door gebruik te maken van een eenvoudig natuurkundig principe: als een fluïdum door een steeds nauwer wordende doorgang gevoerd wordt zoals bijvoorbeeld getekend in figuur 1 in een 30 zogenaamde venturibuis 1, dan zal de stroomsnelheid van dat fluïdum verhoogd worden, waardoor plaatselijk de druk verlaagd wordt.Yet there is a way to get energy from running water without the adverse effects of a water mill and with the aforementioned benefits of a water mill. Namely by making use of a simple physical principle: if a fluid is passed through an increasingly narrow passage as for example drawn in figure 1 in a so-called venturi tube 1, the flow rate of that fluid will be increased, whereby the pressure will be lowered locally is going to be.
Deze verlaging van de druk kan uitgerekend worden met de Wet van Bemouilli.This reduction in pressure can be calculated with the Law of Bemouilli.
