Balance of liquid-phase turbulence kinetic energy equation for bubble-train flow
(Atomic Energy Soc Japan, Tokyo, 2004)
In this paper the investigation of bubble-induced turbulence using direct numerical simulation (DNS) of bubbly two-phase flow is reported. DNS computations are performed for a bubble-driven liquid motion induced by a regular ...
Experimental and numerical investigation of heat exchanger built in solid fuel household furnace of an original concept
(Elsevier Science Sa, Lausanne, 2005)
This paper presents selected results obtained by experimental investigation and modeling of flow and heat transfer processes, considering heat exchanger built within an originally developed concept of a household furnace, ...
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 ...
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 ...
A new 3-DOF spatial parallel mechanism for milling machines with long X travel
(Elsevier, Amsterdam, 2005)
It is well known that the shape and volume of the workspace are one of the greatest weaknesses of parallel kinematic machine tools (PKM). Hexaglide and Triaglide mechanisms are examples where workspace extension is achieved ...
Cross-sections and transport properties of F- ions in Ar, Kr and Xe
(Elsevier Science Bv, Amsterdam, 2009)
The aim of the current work is to determine with relatively high accuracy the elastic momentum-transfer cross-sections of F- ions in collisions with noble gases Ar, Kr and Xe. We have applied a simple form of momentum-transfer ...
Fracture properties of multiphase alloy MP35N
(Elsevier Science Sa, Lausanne, 2003)
This paper addresses the fracture properties of commercially cold-drawn (53%) MP35N (35% Co, 35% Ni, 20% Cr, and 10% Mo) in both the cold-worked and the cold-worked and aged conditions. MP35N is a superalloy that exhibits ...
New modular concept for the helium cooled pebble bed test blanket module for ITER
(Elsevier Science Sa, Lausanne, 2005)
Starting from the latest European design of the HCPB blanket for the DEMO a test blanket module for ITER has been deduced. The paper describes the new design and presents the rational of the design choices and the results ...
Modeling of perforation of plates and multi-layered metallic targets
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The perforation of monolithic and multi-layered thin metallic plates by flat-ended cylindrical penctrator is considered. The most relevant analytical penetration models with their most important assumptions, basic process ...
The influence of heat exchanger performances on the design of indirect geothermal heating system
(Elsevier Science Sa, Lausanne, 2004)
Geothermal water can be used for heating objects both by direct or indirect systems. Indirect heating system with supplementary heat source is analyzed in this paper, and mathematical model that includes heat transfer in ...
