EXPERIMENTAL OBSERVATIONS ON EFFICIENCY DIFFERENCE BETWEEN HELICAL AND STRAIGHT BLADED VERTICAL AXIS WIND TURBINES [PDF]
Journal of Engineering Science (Chişinău), 2020 While in operation, the straight bladed vertical axis wind turbines (VAWTs) are affected by the variations in loadings that result in torque and power oscillations. This problem is considered to be solved by adopting helical blades. However, the way this

A hybrid analytical and discrete based methodology to calculate path scallop of helical toroidal cutter in five-axis milling [PDF]
FME Transactions, 2018 This paper presents a new method to calculate path scallop height of toroidal cutter during free-form surface machining in five-axis milling. The scallop height was defined as the distance between the tool intersection point and the normal point on the ...

Effects of pitch angle and damping on stresses in helical spring.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986 The effects of the pitch angle and damping on stresses in the helical spring are investigated by using the finite element method. In the static analysis, the effects of the pitch angle and the number of active coils on the maximum principal stress, which is a primary cause of the fatigue failure, are discussed and it is pointed out that there is a ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
