PARALLELIZATION OF ASSEMBLY OPERATION IN FINITE ELEMENT METHOD
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The efficient codes can take an advantage of multiple threads and/or processing nodes to partition a work that can be processed concurrently. This can reduce the overall run-time or make the solution of a large problem ...
ON CFD INVESTIGATION OF RADIAL CLEARANCE OF LABYRINTH SEALS OF A TURBINE ENGINE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Fluid flow in labyrinth seals of a turbine engine is described. The aim is to describe numerical calculations of fluid flow in labyrinth seals and evaluate the calculated data for different settings of radial clearance of ...
HEAT TRANSFER ENHANCEMENT AND FRICTION IN DOUBLE PIPE HEAT EXCHANGER WITH VARIOUS NUMBER OF LONGITUDINAL GROOVES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
It has been found out that heat exchangers with longitudinal grooves produce better heat transfer than those without longitudinal grooves. However, up to now, there have been few investigations and applications of longitudinal ...
Newmark algorithm for dynamic analysis with Maxwell chain model
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
This paper investigates a time-stepping procedure of the Newmark type for dynamic analyses of viscoelastic structures characterized by a generalized Maxwell model. We depart from a scheme developed for a three-parameter ...
APPLICATION OF FMEA METHODOLOGY FOR CHECKING OF CONSTRUCTION’S PROJECT DOCUMENTATION AND DETERMINATION OF THE MOST RISK AREAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The article deals with an innovative method designed to check project documentation of buildings at the design stage, specifically exploring the possibility to implement FMEA and PDCA methodologies. Based on performed ...
A COMPARISON OF TWO MODAL ANALYSIS METHODS: AN IMPACT HAMMER VERSUS LASER VIBROMETRY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
This paper presents a comparative experimental-analytical study on the performance of Multi-Input Single-Output (MISO) and Single-Input Multi-Output (SIMO) techniques to identify the modal properties of a cantilever beam. ...
MODELING OF MATERIAL BALANCE FROM THE EXPERIMENTAL UCG
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The underground coal gasification is a continually evolving technology, which converts coal to calorific gas. There are many important parameters in this technology, which are difficult to measure. These parameters include ...
PROPERTIES OF A DIFFERENTIAL SEQUENCE BASED UPON THE KUMMER-SCHWARZ EQUATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
In this paper, we determine a recursion operator for the Kummer-Schwarz equation, which leads to a sequence with unacceptable singularity properties. A different sequence is devised based upon the relationship between the ...
USING THE AUTOMATIC VECTORISATION METHOD IN GENERATING THE VECTOR ALTIMETRY OF THE HISTORICAL VLTAVA RIVER VALLEY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The article describes, in detail, the generation procedure of vector altimetry of an upper and middle course of the Vltava River historical valley. By the historical valley, the shape of the river valley before the ...
Additive Laser Barcode Printing on High Reflective Stainless Steel
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
In this paper, the process of an additive laser marking on stainless steel parts for barcode printing is presented. It is based on the use of one transition metal oxide chemically-well bonded to the stainless steel substrate, ...
