1. Investigating the Performance of Coated Carbide Insert in Hard Steel Helical Milling

Navid Molla Ramezani; Behnam Davoodi; Mojtaba Rezaee Hajideh

Volume 11, Issue 3 , September 2018, Pages 1-9

  Helical milling is an alternative hole-making machining process which presents several advantages when compared to conventional drilling. In the helical milling process, the tool proceeds a helical path while rotates around its own axis. Due to its flexible kinematics, low cutting forces, tool wear, ...  Read More

5. Evaluating the Effect of Operating Conditions on Temperature Variation Rate of Inner Walls and Inside Inflated Air of Pneumatic Tires

Moslem Namjoo; Hossein Golbakhshi; Farhad Khoshnam; Ahmad Soleimani

Volume 11, Issue 3 , September 2018, Pages 45-53

  For rolling pneumatic tires, the thermal induced effects are mainly resulted from visco-elastic behaviour of rubber parts and dissipation of stores strain energy during the cyclic deformations. It is noted that the operating conditions crucially contribute to the rubber hysteresis effect and temperature ...  Read More

6. Thermal Optimization of an Array of Needle-Shaped using Constructal Theory

Maryam Hoseinzadeh; Afshin Ahmadi Nadooshan; Morteza Bayareh

Volume 11, Issue 3 , September 2018, Pages 55-61

  In the present paper, the constructal theory is employed to determine the optimal configuration of three rows of needle-shaped fins. The heat transfer across the fins is due to laminar forced convection. Second order upwind scheme is used for discretization of the diffusion terms of governing equations. ...  Read More

7. Investigating Cooling Effect with Compound Angle on the Combustion Chamber Wall Temperature

Mohamad Reza Nazari; Behrooz Shahriari; Farhad Sebghatollahi

Volume 11, Issue 3 , September 2018, Pages 63-73

  Increasing the temperature of the turbine entrance gases increases the efficiency of the gas turbine cycle. Under these conditions, the combustion chamber wall temperature also increases, while there is no high temperature resistance alloy fitted with air motors. Therefore, it is necessary to use cooling ...  Read More
