The paper presents a method for monitoring the flow conditions in pipelines in the case of transport of crystallising water slurries forming scale. The method’s core is the ability to calculate the equivalent pipeline diameter under varying flow conditions in industrial practice. The method was successfully tested in the laboratory and employed in an industrial plant.
This paper is devoted to numerical studies of composite structures with delaminations made with the use of CDT. Analysis of temperature distribution provides the opportunity to determine the geometry of subsurface defects. Results confirm the validity of the FE model in comparison to previous experimental investigations.
In this paper the analysis of performance characteristics of a cross flow fan working as an element of the unit incorporating heat exchanger as well as performance characteristics of the unit are presented. These experimental results were basic for consideration of pressure losses arising as an effect of direct connection of a cross flow fan and a heat exchanger located in the charging zone of the...
This paper presents an analysis of momentum, angular momentum and heat transfer during the unsteady natural convection in micropolar nanofluids. Presented phenomena are modelled in the vicinity of a vertical plate and heat flux which rises suddenly at a given moment, using the boundary layer concept. Differential equations of angular momentum conservation are used according to the theory of micropolar...

In this paper some selected problems dealing with an influence of different throttling conditions on the flow structure inside a cross flow fan working in a unit incorporating a heat exchanger as well as on aerodynamic performances of a cross flow fan and unit have been studied. Different experimental and numerical methods have been used to verify and confirm selected flow phenomena. The local pressure...
