Work optimization for rotary regenerative air preheater based on an increase of heat capacity of the matrix and reduction of leakage in seal clearances
(China International Conference Center for Science and Technology, 2013)
The paper shows a reconstruction of rotary regenerative air preheater in purpose of increase of it's energy efficiency. The increase of matrix heat capacity was examined with minimal modifications to geometry of heat ...
Scenario razvoja loma u rotorskom bageru / Scenario of fracture development in bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2013)
Produženi rad rotorskog bagera (BWE) u teškim radnim uslovima može dovesti do otkaza mašina. Kod veoma važnih elemenata konstrukcije, može dovesti do katastrofalnog loma. Lociranje važnih elemenata konstrukcije je od ...
Elementi modifikacije i osetljivosti dinamičkih parametara / Elements of dynamic parameters modification and sensitivity
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
Promene na konstrukcijama mogu izazvati promene u strukturnim matricama nekih elemenata. U zavisnosti od vrste konstrukcije, kao i od željenih promena u njoj, moguće je menjati veću ili manju grupu elemenata. U ovom radu ...
Wind energy resource development in Ethiopia as an alternative energy future beyond the. dominant hydropower
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Over the centuries, energy has been supplied by wood, coal, oil and natural gas, as well as by uranium. All these energy sources are limited and create pollution problems. This has led countries to focus on a sustainable ...
Explicit parametric method for optimal spur gear tooth profile definition
(Trans Tech Publications Ltd, 2013)
The gear tooth profile has an immense effect on the main operating parameters of gear pairs (load capacity, working life, efficiency, vibrations, etc). In current engineering research and practice, there is a strong need ...
