CARBURANTS ALTERNATIFS
ISBN: 9786208095901 / Francuski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. De nombreuses recherches ont essayé de remplacer le diesel par la pourghère et ont confirmé qu'avec des changements mineurs dans le moteur, l'efficacité du moteur diesel peut être améliorée de façon marginale. Mais en raison de la viscosité plus élevée de la pourghère, la capacité d'écoulement de la pourghère est moindre, ce qui constitue un inconvénient majeur pour l'augmentation de l'efficacité du moteur. Pour surmonter ce problème d'écoulement, il est prévu dans le présent travail d'utiliser des nanofluides. En outre, le travail est prévu avec le B20 pour varier la...

Performance Analysis of an Optimized Asymmetric MLI
ISBN: 9786204717371 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Standalone inverters based on solar photovoltaic (SPV) systems have become increasingly popular in domestic and commercial applications. Solar photovoltaic (PV) systems are becoming more important to the world in the twenty-first century to meet the electricity demand. However, due to variations in temperature or irradiation, the output voltage of the SPV system has larger ripples and, as a result, the output power is often variable. The MPPT algorithm is implemented using an appropriate DC-DC converter to address these hassles.

Influence of Tool Rotation on the Output Parameters of the EDM Process
ISBN: 9786202923781 / Angielski / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Electric Discharge Machining (EDM) is an acclaimed non-conventional machining process that is used for machining of hard or geometrically complex and electrically conductive materials which are extremely difficult to machine by conventional methods. One of the foremost demerits of this process is its very low material removal rate (MRR). For this, researchers have proposed some modifications, such as providing rotational motion to the tool or workpiece, mixing of conducting fine powders (such as SiC, Cr, Al, graphite etc.) in the dielectric, providing vibrations to either the tool or the...

STUDY OF SAND EROSION IN FRANCIS TURBINE USING CFD
ISBN: 9786208119386 / Angielski / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Erosion of material surface due to collision of solid particles has been a challenge to several fields of engineering. Despite centuries of investigation and research, the exact phenomenon of erosion of surface by solid particles has not been fully understood. Erosive wear of hydro turbine components generally depends on different parameter such as concentration, size and shape of sediments particle, velocity of flow, properties of base material of turbine component. In this work, a two-way coupled Eulerian-Lagrangian approach is employed to calculate the erosion in various components of...
