Summary

The main focus of the special issue is to bring out the innovative research works accomplished in the diverse fields of fluid dynamics and functional materials. Research works pertaining to fluid motion (liquid and gas) inside the containers with different profiles are invited for publication. Also, challenges are found while preparing the nanofluids and dispersion stability for long-run use. As far as the functional materials are concerned the research works related to building materials, materials for automobiles, materials for the green environment and sustainability are in great demand. Finally, the materials are required to achieve energy conservation in industries and domestic applications. Thus, this special issue invites the articles to deal with the challenges of the aforementioned subjects.

The Effect of Different Freeze-Thaw Cycles on Mortar Gas Permeability and Pore Structure
Wei Chen, Ao Xu, Hejun Zhang, Mingquan Sheng, Yue Liang, Frederic Skoczylas
FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.6, pp. 1623-1636, 2023, DOI:10.32604/fdmp.2023.025083

Abstract Two different freeze-thaw cycles (FTC) are considered in this study to assess the related impact on gas permeability and micro-pore structure of a mortar. These are the water-freezing/water-thawing (WF-WT) and the air-freezing/air-thawing (AF-AT) cycles. The problem is addressed experimentally through an advanced nuclear magnetic resonance (NMR) technique able to provide meaningful information on the relationships among gas permeability, pore structure, mechanical properties, and the number of cycles. It is shown that the mortar gas permeability increases with the number of FTCs, the increase factor being 20 and 12.83 after 40 cycles for the WF-WT and More >

Analysis of the Emissions and Performance of a Diesel Engine Using Pumpkin Seed Oil Methyl Ester with Different Injection Pressures
Surendrababu Kuppusamy, Prabhahar Muthuswamy, Muthurajan Kumarasamy, Sendilvelan Subramanian
FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.4, pp. 1003-1014, 2023, DOI:10.32604/fdmp.2022.022262

Abstract Biodiesel fuel is a potential alternative energy source for diesel engines due to its physiochemical characteristics relatively similar to those of traditional diesel fuel. In this study, the performance, emission, and combustion features of a mono cylinder DI diesel engine are assessed using 20% Pumpkin seed methyl ester (PSOME20) and considering varying injection pressures (200, 220, 240, and 260 bar). The considered Pumpkin seed oil is converted into pumpkin biodiesel by transesterification and then used as fuel. The findings demonstrate that the Brake Thermal Efficiency (BTE) of PSOME20 can be raised by 1.68%, and the More >

Analysis of a Cashew Shell and Fly Ash Rich Brake Liner Composite Material
R. Selvam, L. Ganesh Babu, Joji Thomas, R. Prakash, T. Karthikeyan, T. Maridurai
FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.3, pp. 569-577, 2023, DOI:10.32604/fdmp.2022.022187
（This article belongs to the Special Issue: Advances in Fluid Dynamics and Functional Materials)
Abstract Hybrid materials collected from organic and inorganic sources, which are traditionally used as brake lining materials, generally include fly ash, cashew shell powder, phenolic resins, aluminium wool, barites, lime powder, carbon powder and copper powder. The present research focuses on the specific effects produced by fly ash and aims to provide useful indications for the replacement of asbestos due to the health hazards caused by the related fibers. Furthermore, the financial implications related to the use of large-volume use of fly ash, lime stone and cashew shell powder, readily available in most countries in the More >

Analysis of Friction and Heat Transfer Characteristics of Tubes with Trapezoidal Cut Twisted Tape Inserts
Shrikant Arunrao Thote, Netra Pal Singh
FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.3, pp. 711-722, 2023, DOI:10.32604/fdmp.2022.021651
（This article belongs to the Special Issue: Advances in Fluid Dynamics and Functional Materials)
Abstract The thermo-hydraulic properties of circular tubes with a twisted tape inside (used accordingly to induce turbulence and enhance heat transfer through the tube wall) are described for Reynolds Numbers ranging from 830 to 1990. Tapes twisted with the three distinct twist ratios are considered, namely, 6, 4.4 and 3. Air is used as the working fluid in several tests. For the sake of comparison, the standard tube with no insert is also examined. It is shown that in the presence of the twisted tape, the ‘frictional factor’, ‘Nusselt Number’ and the ‘thermal performance factor’ are More >

Study on the Influence of a Wake Vortex on an ARJ21 Aircraft Using the Strip Method
Weijun Pan, Jingkai Wang, Hao Wang, Yuming Luo
FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.5, pp. 1495-1509, 2022, DOI:10.32604/fdmp.2022.019018
（This article belongs to the Special Issue: Advances in Fluid Dynamics and Functional Materials)
Abstract A model for the vortex distribution in the wake of an aircraft is elaborated to investigate the wake influence on the behaviour of other aircrafts potentially interacting with it. As a realistic case, the interaction of an ARJ21 aircraft with a (leading) A330-200 aircraft is considered. Different distances are considered, namely, 6 km, 7 km, 8 km, 9.3 km, and 10 km. Simulations based on the used wake dissipation mechanism are used to investigate different conditions, namely, the ARJ21 in take-off and level flight and the changes induced in the related lift by the front More >
