Non steady state thermal conductivity of ABS was estimated using an analytical approach in a Cold Climate Chamber at ?10?C and ?14?C. Two hollow cylinders of ABS of varying thickness were used to estimate the conductivity. The material was porous but the porosity was unknown. This paper is a case study to understand, if it is reasonable to estimate the thermal conductivity using the analytical varying ...

Nowadays the concept of Industry 4.0. and the relating intelligent manufacturing system are getting more and more current and well-known. In the past years the outstanding development of different areas such as information technology computer science, machining, robotics and so on, made possible a comprehensive transformation of the manufacturing systems. Present paper aims to give a general overview ...

Numerical study of atmospheric ice accretion on two non-rotating circular cylinders in tandem arrangement was carried out at different operating and geometric conditions. To validate the numerical model, initially the results of ice accretion on single circular cylinder were compared with the experimental data obtained from CIGELE atmospheric icing research wind tunnel (CAIRWT) [1, 2]. A good agreement ...

Water hammer phenomenon involves the transformation of kinetic energy in pressure energy, this transformation occurs as the fluid conditions change inside the pipe in quite a short time. Industry requires to affront frequent flow interruptions in pipe systems due to the closing of valves or stopping of pumping equipment. This phenomenon can initiate serious damages like destruction of the pipe system ...

The application of capacitive sensing technique is widely distributed in different physical domains primarily because of the diversity in dielectric permittivity and due to its minimum loading error and inertial effects. Atmospheric ice is a complex mixture of water, ice and air which is reflected in its complex dielectric constant. There are many existing atmospheric icing sensors but only few are ...

Study of atmospheric ice accretion on a non-rotating vertical circular cylindrical object was carried out at dry and wet ice conditions. Both numerical and experimental techniques were used during this study. 3D numerical study was carried out using computational fluid dynamics based approach, whereas experimental study was carried out at Cryospheric Environmental Simulator ‘CES’ in Shinjo, Japan. ...

Manufacturers in the resourceful Northern Peripheral and Arctic (NPA) region are mostly small and medium-sized enterprises (SMEs). Facing challenges primarily caused by the size and location of enterprises, these SMEs are constantly driven to take new measures to survive from the fierce competition against its domestic and international competitors, under the industrial environments of globalization ...

The problem of global warming raised up interest to renewable energy. To reduce cost of wind energy is challenge. Before building of wind park such conditions like: average wind speed, direction, time for each wind, probability of icing. Also have to be considered amplitude of wind changes and their amount. This thesis presents Nygårdsfjellet wind turbine park data analysing for determining power ...

With the development of increasing globalization of markets, the small and medium-sized enterprises (SMEs) are necessary to improve their innovation ability, and enhance their competitiveness in the global market. This project analyzes the global and region current situation of SMEs, and then provide the conclusion of advantages and challenges of SMEs, especially the sort of small manufacturing ...

Nowadays, many manufacturing companies need to face competition both in domestic and international level. Due to this circumstance, manufacturers recognize that one useful method to enhance their competence is reducing the lead-time of manufacturing. There are many researchers focused on minimize the time of actual cutting, tool path optimization and energy consumption optimization etc. However, few ...
