Enhancement of heat transfer coefficient using Diamond shaped roughness on the absorber plate of solar air heater
Solar collector (Air heater) has low thermal efficiency due to the low thermal conductivity between Air and absorber plate. So there is a need to enhance the thermal conductivity between air and absorber plate. This leads higher temperature to absorber plate and hence maximum thermal losses occurs to environment .It can be made possible by creating artificial roughness on absorber plate .There ...
متن کاملExperimental Study of Transient Pool Boiling Heat Transfer under Exponential Power Excursion on Plate - Type Heater
Conduction and single-phase convective heat transfer are well understood phenomena: analytical models [1] and empirical correlations [2] allow capturing the thermal behavior of plate-type fuels or heaters in contact with a single-phase coolant. On the other hand, transient boiling heat transfer is a scarcely studied and much less understood phenomenon. Although, earlier studies have shown that ...
متن کاملModel for Aggregated Water Heater Load Using Dynamic Bayesian Networks
The transition to the new generation power grid, or “smart grid”, requires novel ways of using and analyzing data collected from the grid infrastructure. Fundamental functionalities like demand response (DR), that the smart grid needs, rely heavily on the ability of the energy providers and distributors to forecast the load behavior of appliances under different DR strategies. This paper presen...
متن کاملExperimental Analysis of Solar Water Heater Using Pulsating Heat Pipe
Solar energy is used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. The CLPHP system described in this study relies on the natural forces of gravity and capillary action and does not require an external power source. The flat plate collector consisted of a 2 mm thick sheet of Aluminum ...
متن کاملFabrication of submicron-diameter silica fibers using electric strip heater.
In nonlinear optical frequency conversion process, it is desirable to maximize the product of the intensity of pump laser and the interaction length in order to achieve maximum conversion efficiency. In this paper, long and unbroken submicron-diameter optical fibers with low optical loss about 0.1dB/cm were fabricated with a new drawing process by heating the conventional single mode fiber usin...
