https://doi.org/10.4467/2353737XCT.16.093.5492This paper presents comparison of calculation methods of the required thickness of the tube sheet in the shell and tube heat exchanger compatible with the standards of the European standard PN - EN 13445-3, and the guidelines of the Polish Office of Technical Inspection (UDT). Details of the methods are illustrated by numerical examples – (calculations) for the selected design of the tubesheet.

https://doi.org/10.4467/2353737XCT.16.107.5506The paper presents the results of experimental investigation of the hydrodynamics in unbaffled stirred vessel with eccentric Rushton turbine configuration. Basing on flow visualisation. the main flow features were determined. Laser Doppler Anemometry measurements provided radial and axial components of the mean flow velocity vectors. The obtained data of power consumption allowed to determine the impact of the impeller eccentricity ratio e/R on the power number Ne.
