The various thermoelectric effects in relation to thermodynamic conversion of heat to work are as follows: 1. Seebeck Effect 2. Peltier Effect 3. Thomson Effect 4.Joule Effect. 1. Seebeck Effect: If two dissimilar materials are joined to form a loop and two junctions maintained at different temperatures, an e.m.f. will be set up around the loop. The magnitude of current [...]
In this article we will discuss about the design of wind turbine rotor with the help of suitable diagrams. In a propeller type wind turbine, the following two forces operate on the blades: 1. Axial Thrust: It acts in the same direction as that of the flowing wind stream. 2. Circumferential Force: It acts in the direction of wheel rotation [...]
In this article we will discuss about the design of electro gas dynamic generator with the help of a schematic diagram. Also learn about the advantages of electro gas dynamic generator over MHD systems. 'Carona electrode' at the entrance of the duct generates electrons. This ionised gas particles are carried down the duct with the neutral atoms and the [...]
