EPJ ST Special Issue: Transport Phenomena of Nanofluids in Cavities - Current Trends and Applications
- Published on 01 October 2021
The studies of flows within cavities are used to model several experimental analysis arise in many branches of engineering, technology and medical. The fluid flow in cavities is one of the most preferred geometries to examine the characteristics of some design parameters on the thermal performance of simulated systems. The impact of flow rate and cavity size on two-dimensional flow in a rectangular cavity is used to analyse the clearance time of debris in renal pelvis. The studies on cavity flows play a significant role to enhance the performance of short-dwell coating, removal of species from structured surfaces, mixing and flow in drying devices. The characteristics of drag-reducing riblets can be analysed by using the eddy structures obtained from the driven-cavity flows. The studies on enclosures with time-dependent thermal boundary conditions play a vital role to improve the effectiveness of the heat removal from electronic components and food storage facilities. Various type of cavities such as square, rectangle, triangle, trapezoidal, hexagonal, C, D, F, H, I, L, T, U, V, X, and Y – shaped have been analysed to examine the transport phenomena of varies fluids.
In the last decade, nanofluids have gained significant attention due to their enhanced thermo-physical properties such as thermal conductivity, viscosity, density, and specific heat capacity. A wide range of applications for nanofluids in different areas such as biomedical, lubrication, surface coating, petroleum industry, environmental remediation, and electronics cooling systems have been reported in the literature. Buongiorno have analysed seven slip mechanisms such as inertia, Brownian diffusion, thermophoresis, diffusiophoresis, Magnus effect, fluid drainage, and gravity and concluded that Brownian diffusion and thermophoresis are important slip mechanisms in nanofluids. Based on this finding, many researchers have adopted various Newtonian and non-Newtonian fluid models to analyse the transport phenomena of nanofluids. Tiwari and Das manifested another nanofluid model which accounts the thermophysical properties of base fluids such as water, ethylene glycol, oil and various kinds of nanoparticles such as metals, metallic oxides, semiconductors, ceramics and carbon nanotubes to prepare nanofluids. Several researchers have analysed the transport phenomena of various nanofluids with different combination of base fluid and nanoparticles by using Tiwari and Das model.
In our last issue, the transport properties of non-Newtonian nanofluids were analysed over different geometries such as plate, stretching sheet, cone, and cylinder. The aim of this special issue is to comprise original theoretical/experimental research articles which address the recent developments and research efforts on the transport phenomena of nanofluids in cavities with the purpose to provide guidelines for future research directions.
The topics include, but are not limited to:
- Modelling nanofluid flows in cavities: challenges and applications
- Nanofluid flow in various cavities (square, rectangle, triangle, trapezoidal, etc.)
- The impact of various external forces on nanofluid cavity flows
- Numerical methods for solving cavity problems
- Nonlinear dynamics and chaos
We would like to invite the authors to submit their original research articles on transport phenomena of nanofluids in cavities.
Articles should be submitted to the Editorial Office of EPJ ST via the submission system, and should be clearly identified as intended for the topical issue “Transport phenomena of nanofluids in cavities - Current Trends and Applications”.
