This paper sets out to examine a small absorption chiller that uses the pair LiBr/ H2O with a 4.5 kW nominal capacity, using theoretical modeling and the characteristic equation method. The idea is to compare two ways of simulating and evaluating absorpti... see more

The rapidly changing environmental conditions, and has created new challenges for higher education. University of academic entrepreneur who not only meet the needs and expectations of their environment is diverse, rather, its programs and operational proc... see more

We develop a finite volume characteristic method for the solution of the advection-diffusion equations which model the contaminant transport through porous medium. This method uses a second order Runge-Kutta approximation for the characteristics within th... see more

Sasyk (Kunduk) – estuary in the North-Western Black Sea region, is located 120 kmsouth-west of Odessa. In 1979–1980 Sasyk was separated from the sea by a dam, connected by a canal with the Danube and transformed into a reservoir. The fauna of Sasyk underw... see more

In this article, a geometrical model of different microtextures is established for an axial piston pump valve plate. A finite differential method was used to solve the Reynolds equation for the oil film thickness and pressure, which were simulated under d... see more

Combustion instability in rocket engines is accompanied by large-amplitude pressure fluctuations in the combustion chamber and (or) intense vibration of the load-bearing structural elements. Unstable operation leads to a decrease in thrust, specific impul... see more

Achievement of student academic achievement is influenced by various factors both inner factor of student (internal factor) and factor from outside student self (external factor). One of the external factors affecting student achievement is the campus env... see more

In this study, the energy equation and normalized wave function were obtained by solving the Schrödinger equation analytically utilizing the Eckart-Hellmann potential and the Nikiforov-Uvarov method. Fisher information and Shannon entropy were investigate... see more

The field of rough turbulent flow occupies an important place in the practical applications of hydraulic engineer. It is for this reason that the present study is interested in the most important parameters of this flow namely the characteristic length, t... see more
