The determinations of heat collection rate and heat loss coefficient are crucial for the evaluation of in service water-in-glass evacuated tube solar water heaters. However, the direct determination requires complex detection devices and a series of stand... see more

CFD simulation investigated turbulent flows in equal gas pipeline tees, in which the gas flow completely moves from the main line to the branch. The study was performed for tees of different geometry – stamped with different bending radii of the transitio... see more

The authors offer conferencing method for determining the power loss coefficient for the contact network. Authors have received expressions for the equivalent value of loss coefficient for the existing power schemes contact network. 

The researches of the influence of variation coefficient of inter-train interval on the losses of electric power in traction line are discussed.

Economic dispatch is an important optimization problem in power system planning. This article presents an overview of the economic dispatch formulation, its objective, loss coefficient determination, and a case study. In the case study, different scenario... see more

This study presents a numerical investigation of flow and rheological behaviour of activated sludge. These materials are usually driven by pumps in wastewater treatment plants. Because of the correct sizing of the pipeline systems, which is of great impor... see more

Heat transfer through dry and wet Svalbard reindeer (Rangifer tarandus platyrhynchus) summer and winter midback fur samples was studied in a wind tunnel. A light wetting water spray simulated heavy fog, mist or light rain, while heavy soaking simulated he... see more

Tissues of fresh vegetables are characterized by the high quantity of moisture (80…96 %), active metabolism, low resistance to mechanical lesions, are spoiled fast. Metabolism in cells of tissues, so mass losses, depends on the content of water and dry su... see more

The study proposes a theoretical development in order to determine the relationship which governs the discharge coefficient of a contracted triangular weir. The theoretical approach takes into account the effect of the approach flow velocity which can be ... see more
