Novel variant syndrome associated with congenital hepatic fibrosis
(BAISHIDENG PUBLISHING GROUP INC, 2015)Congenital hepatic fibrosis is part of many different malformation syndromes, of which oculo-encephalohepato-renal syndrome is the most common. These syndromes largely overlap, and so accurate classification of individual ... -
The nucleophilicity equalization principle and new algorithms for the evaluation of molecular nucleophilicity
(ELSEVIER SCIENCE BV, 2016)In this work, we have attempted to explore whether the nucleophilicity equalization principle can be conceived analogous to the well-established electronegativity, hardness, and electrophilicity equalization principle. ... -
NUGGET FORMATION EFFECTS IN RESISTANCE SPOT WELDED DIFFERENT STEEL SHEETS
(UNIV ZAGREB FAC MECHANICAL ENGINEERING & NAVAL ARCHITECTURE, 2017)In this study, galvanized and austenitic stainless steel sheets were joined to each other by using resistance spot welding. The thicknesses of the galvanized steel and austenitic stainless steel are 0.93 and 1.03 mm, ... -
Numerical analysis of heat transfer due to slot jets impingement onto two cylinders with different diameters
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)A numerical investigation has been performed two-dimensional slot impingement onto two heated cylinders with different diameters turbulent flow conditions. Height of slot jet is taken as constant for all cases. The study ... -
Numerical Analysis of Viscoelastic Fluids in Steady Pressure-Driven Channel Flow
(ASME, 2012)The developing steady flow of Oldroyd-B and Phan-Thien-Tanner (PTT) fluids through a two-dimensional rectangular channel is investigated computationally by means of a finite volume technique incorporating uniform collocated ... -
NUMERICAL INVESTIGATION INTO HEAT TRANSFER FOR THREE-DIMENSIONAL PLATE FIN HEAT EXCHANGERS WITH FINS PLACED PERPENDICULAR TO FLOW
(UNIV ZAGREB FAC MECHANICAL ENGINEERING & NAVAL ARCHITECTURE, 2013)In the present study, the potential of rectangular fins with a 30 degrees and 60 degrees angle and 10 mm offset from the horizontal direction perpendicular to flow for heat transfer enhancement in a plate fin heat exchanger ... -
Numerical investigation of fouling on cross-flow heat exchanger tubes with conjugated heat transfer approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)Although fouling on heat exchanger tubes is extensively investigated, due to the lack of energy resources, the effects of fouling on heat exchangers is still an important area of study and gaining more and more attention ... -
NUMERICAL INVESTIGATION OF THE EFFECT OF INSULATION ON HEAT TRANSFER OF THERMAL BRIDGES WITH DIFFERENT TYPES
(VINCA INST NUCLEAR SCI, 2016)In the present study, the effects of dfferent types thermal bridges formed by beams for floor-wall junctions in reinforced concrete structures, with and without balconies, and the optimum configuration of the insulation ... -
Numerical simulation of the stalled flow within a vaned centrifugal pump
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2004)The main goal of the present work is to analyse the numerical simulation of a centrifugal pump by solving Navier-Stokes equations, coupled with the 'standard k-epsilon' turbulence model. The pump consists of an impeller ... -
