1. Solid-phase effects on the performance of a centrifugal slurry pump using computational fluid dynamics

Mohammad Reza Aligoodarz; Mohsen Dalvandi; Abdollah Mehrpanahi

Articles in Press, Accepted Manuscript, Available Online from 17 May 2020


  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 (PCM) affected by Heat Transfer Fluid (HTF) Flow Parameters

Omid Ahmadi; Sahand Majidi; Pooyan Hashemi Tari

Articles in Press, Accepted Manuscript, Available Online from 09 May 2020


  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


  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

5. Numerical investigation of upward air-water annular, slug and bubbly flow regimes

Maryam Hassani; Mohammad Bagheri Motlagh; Ramin Kouhikamali

Volume 9, Issue 2 , Winter and Spring 2020, , Pages 331-341


  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


  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


  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

8. Numerical simulation of laser beam welding of Ti6Al4V sheet

M. Azizpour; M. Ghoreishi; A. Khorram

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


  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
