Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The flow behavior through an asymmetric diffuser is investigated in the present study. The shapes of the inlet velocity profile on the diffuser performance are studied and the flow is treated as two dimensional. From the present st…udy it was found that the used level of the Re, the diffuser angle, the aspect ratio, and the walls connection are mainly determine the quality of the flow through the diffuser. The results indicated significant effects on the flow pattern and static pressure recovery due to the inlet flow non-uniformity. The case of the inverted uniform shear flow showed almost 13% increase in the pressure recovery with respect to the reference case of the fully-developed turbulent flow. In case of the highest Reynolds number examined in the present work, the phenomenon of high energy redistribution was not observed and the loss level was maintained low. The experimental and numerical results showed a strong effect of the diffuser wall connection down-stream on the flow regime. Small regions with high energy have been observed at this location for the different inlet flow conditions at the highest studied value of the Reynolds number, except for the fully developed flow 148 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Renewable energy generation is becoming more prevalent on today's electric grid. The challenge of increasing the percentage of renewable energy will be dealing with the intermittent nature of renewable sources. This book provides c…ollective information on various solar energy conversion techniques useful for academicians, researchers, and society at large. The understanding of each technology and its associated challenge provides a suitable basis to recognize advantages and drawbacks. More importantly, it gives the technological development of Linear Fresnel Reflector Mirror (LFRM) concentrator. In this book, a study considering the replacement of EWH by Concentrating solar Photovoltaic and thermal system (CSPV/TS) in the highlands of Yerevan region is presented. Analyses demonstrates that electricity and heating domestic water via solar (CSPV/T) energy is simple, reliable, and cost-effective. The model is used to analyze the performance of LFRM concentrating collector parameter such as reflector length, aperture diameter, PV/T receiver, focal distance and temperature at the PV/T receiver with different solar irradiations to increase the thermal efficiency. 188 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The significant advancements in poultry genetics highlight the transition from traditional breeding methods to modern genomic technologies. The evolution of poultry production, which began with the domestication of the red junglefowl,…has seen remarkable improvements in productivity through traditional selection focused on phenotypic traits such as growth rate, egg production, and feed efficiency. While these methods have yielded substantial gains, their limitations underscore the necessity for contemporary genomic tools that facilitate more precise and effective genetic enhancements. The integration of high-throughput -omics datasets, including genomics, transcriptomics, and proteomics, has revolutionized the field of poultry genetics. These technologies enable researchers to analyze vast amounts of biological data. The genetic improvement in poultry including traditional selection and molecular genetic tools. As well as this book emphasizes the role of single nucleotide polymorphisms (SNPs) in genomic selection, which facilitates the identification of genetic variations linked to specific traits, such as disease resistance and feed efficiency.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 64 pp. Englisch.
