Review paper Perturbation Technique
A study on free convective heat and mass transfer flow through a highly porous medium with radiation, chemical reaction and Soret effects

shaik Mohammed ibrahim; Kanna Suneetha; G.V Ramana Reddy

Volume 8, Issue 2 , February 2019, Pages 121-132


  The paper addresses the effects of Soret on unsteady free convection flow of a viscous incompressible fluid through a porous medium with high porosity bounded by a vertical infinite moving plate under the influence of thermal radiation, chemical reaction, and heat source. The fluid is considered to be ...  Read More

Fuzzy motion control for wheeled mobile robots in real-time

Mohammad Falsafi; Khalil Alipour; Bahram Tarvirdizadeh

Volume 8, Issue 2 , February 2019, Pages 133-144


  Due to various advantages of Wheeled Mobile Robots (WMRs), many researchers have focused to solve their challenges. The automatic motion control of such robots is an attractive problem and is one of the issues which should carefully be examined. In the current paper, the trajectory tracking problem of ...  Read More

Calculation of lateral velocity estimation and error discrimination for railway wheelset to avoid sliding

Zulfiqar Ali Soomro

Volume 8, Issue 2 , February 2019, Pages 153-164


  Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes cause of derailment by sliding due to insufficient adhesion ratio. This impropriate balance is pretext owing to contamination and weather procures the disturbances. This perturbation makes hindrances ...  Read More

Research Paper Hydraulic and Pneumatic Systems
Experimental and numerical investigation of bottom outlet hydraulic model

Mahdi Moghimi

Volume 8, Issue 2 , February 2019, Pages 153-164


  Using experimental models along with conducting numerical analysis have been widely used in performance recognition and optimization of hydraulic equipments. Numerical modeling has lower cost rather than experimental one; however practical tests are commonly used because of the hydraulic structure importance ...  Read More

Fuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve

Pardeep kumar Rohilla; Feras Hakkak; Vineet Kumar

Volume 8, Issue 2 , February 2019, Pages 165-174


  Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, ...  Read More

Research Paper Fluid Mechanics
Numerical investigation of vertical and horizontal baffle effects on liquid sloshing in a rectangular tank using an improved incompressible smoothed particle hydrodynamics method

Rahim Shamsoddini

Volume 8, Issue 2 , February 2019, Pages 175-186


  Liquid sloshing is a common phenomenon in the transporting of liquid tanks. Liquid waves lead to fluctuating forces on the tank wall. If these fluctuations are not predicted or controlled, they can lead to large forces and momentum. Baffles can control liquid sloshing fluctuations. One numerical method, ...  Read More

Research Paper Turbulance
Experimental analysis of shock waves turbulence in contractions with rectangular sections

Mohammad Reza Nikpour; payam khosravinia; Davod Farsadizadeh

Volume 8, Issue 2 , February 2019, Pages 187-196


  Formation of shock waves has an important role in supercritical flows studies. These waves are often occurring during passage of supercritical flow in the non-prismatic channels. In the present study, the effect of length of contraction wall of open-channel for two different geometries (1.5 m and 0.5 ...  Read More

Research Paper Fluid Mechanics
Laminar mixing of high-viscous fluids by a cylindrical chaotic mixer

Payam Rahim Masharei; Seyed Mostafa Hosseinalipour; Mohammad Javad moslemani

Volume 8, Issue 2 , February 2019, Pages 197-210


  Laminar mixing of glycerin in a chaotic mixer is carried by means of the blob deformation method. The mixer was a cylindrical vessel with two rotational blades which move along two different circular paths with a stepwise motion protocol. The flow visualization was performed by marking of the free surface ...  Read More

Research Paper Heat and Mass Transfer
Flow field, heat transfer and entropy generation of nanofluid in a microchannel using the finite volume method

Majid Kerdarian; Ehsan Kianpour

Volume 8, Issue 2 , February 2019, Pages 211-222


  In this study, the finite volume method and the SIMPLER algorithm is employed to investigate forced convection and entropy generation of Cu-water nanofluid in a parallel plate microchannel. There are four obstacles through the microchannel, and the slip velocity and temperature jump boundary conditions ...  Read More

Three-dimensional characteristic approach for incompressible thermo-flows and influence of artificial compressibility parameter

Tohid Adibi

Volume 8, Issue 2 , February 2019, Pages 223-234


  In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity ...  Read More
