Abstract
  The centrifugal slurry pump is the most common slurry flow pump used in mining industries. The pump head and efficiency are affected by the size, concentration, and density of solid particle when these pumps are applied for the control of slurries. Because the suspended solids in the liquid could not ...  Read More

3. Numerical study of transient behavior and heat transfer in a phase change material affected by heat transfer fluid flow parameters

Omid Ahmadi; Sahand Majidi; Pooyan Hashemi Tari

Volume 10, Issue 2 , Winter and Spring 2021, , Pages 461-471

http://dx.doi.org/10.22061/jcarme.2020.5941.1754

Abstract
  Phase Change Materials (PCMs) are known to be capable of storing a substantial amount of energy in relatively low volume. Also, since the phase change process occurs in a nearly constant temperature, PCMs are suitable to be used as storage units. The present study focuses on the effect of Heat Transfer ...  Read More

4. Cooling a hot obstacle in a rectangular enclosure by using a MHD nanofluid with variable properties

Milad Darabi Boroujeni; Ehsan Kianpour

Volume 10, Issue 1 , Summer and Autumn 2020, , Pages 101-110

http://dx.doi.org/10.22061/jcarme.2019.2959.1308

Abstract
  In this study, cooling of a hot obstacle in a rectangular cavity filled with water-CuO nanolfuid has been examined numerically. This cavity has an inlet and outlet and the cold nanofuid comes from the left side of the cavity and after cooling the hot obstacle, it goes out from the opposite site. All ...  Read More

http://dx.doi.org/10.22061/jcarme.2019.3893.1453

Abstract
  In this paper, numerical investigation of upward two phase flow of air-water has been studied. Different conditions of flow regimes including annular, wispy annular, slug, churn and bubbly are simulated based on Hewitt and Roberts map, and a good agreement between the experimental data of the map and ...  Read More

6. Experimental study and application of computational fluid dynamics on the prediction of air velocity and temperature in a ventilated chamber

mohammad saeed sharifi; Miralam Mahdi; Karim Maghsoudi Mehraban

Volume 9, Issue 1 , Summer and Autumn 2019, , Pages 107-119

http://dx.doi.org/10.22061/jcarme.2019.3919.1458

Abstract
  The shape of the air flow in the interior is heavily influenced by the air distribution system and the way air enters and exits. By numerically simulating flow by computational fluid dynamics, one can determine the flow pattern and temperature distribution and, with the help of the results, provide an ...  Read More

7. Experimental and numerical investigation of bottom outlet hydraulic model

Mahdi Moghimi

Volume 8, Issue 2 , Winter and Spring 2019, , Pages 153-164

http://dx.doi.org/10.22061/jcarme.2018.1627.1140

Abstract
  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

Volume 4, Issue 2 , Winter and Spring 2015, , Pages 145-154

http://dx.doi.org/10.22061/jcarme.2015.272

Abstract
  This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The butt-joint welds were made using CO2 laser with the maximum power of 2.2 kW in the ...  Read More
