Unsteady Fluid Forces Acting on a Disk Simulating a Hand of Swimmer

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2006
In the early 1970s, the issue of whether propulsion in swimming is due primarily to lift or drag appeared. Prior to that time it was believed that the best way to propel the body forward was to pull the hand directly backwards to use drag forces. Furthermore, the actual motion of a hand in swimming is obviously unsteady and the time-dependent fluid ...

Arrhenius Activation Energy on Viscous and Radiative Heating of Hybridized Chemical Reactive Magnetized‐Casson Nanofluid Flow in Saturated Porous Media With Varied Heat Source/Sink

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study analyzes the influence of Arrhenius activation energy on the chemically reactive, magnetohydrodynamic Casson hybrid nanofluid flow past an exponentially stretching surface embedded in a Darcy–Forchheimer porous medium with a non‐uniform heat source/sink.

State-space model identification and feedback control of unsteady aerodynamic forces

, 2014
Unsteady aerodynamic models are necessary to accurately simulate forces and develop feedback controllers for wings in agile motion; however, these models are often high dimensional or incompatible with modern control techniques.

Dissipative Heat Impact on the Non‐Newtonian Walter's B Nanoliquid Over an Elongating Surface Through a Permeable Medium

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The utilisation of viscoelastic Walter's B nanoliquid in engineering and biomedical applications gained substantial attention because of its ability to provide real‐time fluid behaviour, particularly in the heat flow mechanism. In particular, the flow of viscoelastic fluid over an elongating surface is useful in polymer processing and ...

ANN‐Enabled Analysis of Nanoparticle Aggregation and Hall Effects on Ag‐H2O Nanofluid Flow Over a Spinning Disk With Convective Heating and Thermal Radiation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The exceptional characteristics of nanofluids have turned out to be a significant development in revolutionizing heat transfer mechanisms in several electronic cooling devices and industrial manufacturing processes. The present study deals with the investigation of the second law of thermodynamics applied to the steady MHD fluid flow above a ...

Sedimentation of finite-size spheres in quiescent and turbulent environments

, 2015
Sedimentation of a dispersed solid phase is widely encountered in applications and environmental flows, yet little is known about the behavior of finite-size particles in homogeneous isotropic turbulence.

Nonclassical shallow water flows [PDF]

, 2007
This paper deals with violent discontinuities in shallow water flows with large Froude number $F$. On a horizontal base, the paradigm problem is that of the impact of two fluid layers in situations where the flow can be modelled as two smooth regions ...

Migration and Dispersion Evolution of Exhaled Aerosol in a Ward Under Different Ventilation Modes

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wards with special functions and closure will have a higher risk of viral transmission as aerosols are an important mode of transmission for the SARS‐CoV‐2 virus. In this study, an experimental platform was built to establish the relevant parameters of the aerosol model and the aerosol propagation model according to the experimental results ...

Modeling of Unsteady-State Cake Formation on a Fracture in Produced Water Re-Injection Process (PWRI) [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2010
In petroleum production, Produced Water Re-Injection (PWRI) has earned much interest among disposal methods of the produced water. However, presence of the contaminants in the produced waters usually results in formation damage in well bores and their ...
