Temperature and moisture distributions inside the layer of moist material placed on hot isothermal surface
(Inzhenerno-Fizicheskii Zhurnal, 2001)
The problem of contact drying of a layer of moist material placed on a hot isothermal surface is considered. A system of heat and mass transfer equations and equations for the initial and boundary conditions are proposed. ...
Application of two independent measurement techniques for determination of ductile crack growth initiation
(Springer Netherlands, 1999)
Charpy impact testing of the high strength low-alloyed steel has been performed by simultaneously recording two independent signals. The magnetic emission (ME) and potential drop (PD) techniques were used to determine ...
Evaluation of residual life of steam turbine rotors
(Mezhdunarodnaya Kniga, Moscow, Russian Federation, 1995)
A consideration is given to the problem of determining remaining operational life of steam turbine rotors at the following mechanisms of crack initiation and propagation: low-cycle thermal fatigue, high-cycle fatigue and ...
Analysis of the unstable fracture behaviour of a high strength low alloy steel weldment
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Local brittle zones (LBZ) cause the unstable fracture behaviour of weld metals. This threatens the safe service of welded structures and makes structural assessment procedures difficult. Therefore, the unstable fracture ...
Determination of ductile crack initiation by magnetic emission and potential drop techniques using pre-cracked Charpy specimens
(European Structural Integrity Society, 2002)
Magnetic emission (ME) and potential drop (PD) techniques were used for instrumented Charpy impact testing in order to determine critical crack initiation properties of standard pre-cracked three-point bending specimens ...
Formation of fouling layers on a heat exchanger element exposed to warm, humid and solid loaded air streams
(Elsevier Science Inc, New York, 2002)
In consideration of the very high energy consumption of drying processes it is astonishing and disadvantageous that the majority of industrial dryers are offered and operated without energy recovery. The avoidance of fouling ...
Crystallographic orientations of Ni3Al-based aluminide
(Elsevier Science Inc, New York, 2000)
Inverse pole figures have been plotted to determine preferred crystallographic orientations in a powder-compacted Ni3Al aluminide prealloyed with Fe, Ti and B. The main textural components, although weak, were noticeably ...
Determination of moist air drying ability using chemical potential of water vapour
(Taylor & Francis Inc, Philadelphia, 1998)
A thermodynamically simple method for calculation of chemical potential of water vapour, contained in the unsaturated moist air used as a drying medium in convective dryers, is developed. The introduced concept enables ...
Plane strain fracture toughness of MP35N in aged and unaged conditions measured using modified CT specimens
(Elsevier Science Sa, Lausanne, 2003)
The multiphase alloy MP35N (35% Ni, 35% Co, 10% Mo, 20% Cr) is a high strength, high toughness alloy of choice for several safety-critical applications in aerospace, oil drilling, and biomedical industries. Several previous ...
Analysis of fouling factor in district heating heat exchangers with parallel helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This paper presents the results of measurements of thermal performance of 8 heat exchangers with parallel helical coils. Measurements were conducted in substations in 2 district heating systems in Serbia: Belgrade and ...
