Abstract

Solar energy is available in abundance. It is considered an effective energy source for drying agricultural products. Although it is affordable, open sun drying suffers from both qualitative and quantitative issues caused by unexpected environmental conditions (rain, dust), animals (insects, birds, rodents), and over-or under-drying. Therefore, it is important to introduce a better drying technology to preserve solar energy without deteriorating the quality of the drying product. For that reason, solar dryers have been developed to produce higher drying temperatures and lower relative humidity that will eventually lead to superior drying rates and reduced final moisture contents compared to the conventional open sun drying method. Therefore, not only does the solar dryer meet the requirements of agricultural products, but it also saves energy, time, and money.

Abstract

After get trial of performance of Turbin Pelton Proto X was done with some variations of desain such as percentage of valve opening, nozel distance from center of runner and nozel diameter than get the result of performance. To complete and get perfection need to do simulation and analyse Computational Fluid Dynamic (CFD) uses powerfull engineering software. Based on turbin Pelton Proto X performance result, the velocity of flow is 1.74 m/s. This value will be use for fill parameter conditions when Ansys Fluent is setting up. For this case, it will simulate and analyse of turbin Pelton Proto X with different nozzle diameter and than know the type of flow happen in system of turbin Pelton piping. The result of this CFD analyzing can also give recommendations for development of turbin Pelton Proto X to get higher performance.
