A Derivation of the Colburn Analogy
K. T. Trinh
This paper presents a derivation of the empirical Colburn analogy and discusses its implications. Key words: heat transfer, Colburn, j factor, turbulence, power law, log-law, wall…
The generalised Blasius correlation for turbulent flow past flat plates
K. T. Trinh
This paper presents a theoretical derivation of the empirical Blasius power law correlation for the friction factor. The coefficients in this correlation are shown to be dependent…
On the Sieder state correction and its equivalent in mass transfer
K. T. Trinh
The physical background behind the success of the Sieder-Tate correction in heat transfer is analysed. The equivalent correction for mass transfer correlations is based on the rati…
The wall shear rate in non-Newtonian turbulent pipe flow
K. T. Trinh
This paper presents a method for calculating the wall shear rate in pipe turbulent flow. It collapses adequately the data measured in laminar flow and turbulent flow into a single…
A general correlation for turbulent friction factors in non-Newtonian fluids
Khanh Tuoc Trinh
Correlations of friction factors are presented for the general case of purely viscous non-Newtonian fluids without requiring a priori the adoption of a rheological model. They are…
Turbulent Couette Flow:An analytical solution
Khanh Tuoc Trinh
A simple analytical solution for turbulent plane Couette flow is obtained from a subset of the Navier-Stokes equations. This approach analyses the effect of the unsteady state Lagr…
A Similarity Analysis for Heat Transfer in Newtonian and Power Law Fluids Using the Instantaneous Wall Shear Stress
K. T. Trinh, B. H. P. Wilkinson, N. K. Kiaka
This paper presents a technique that collapses existing experimental data of heat transfer in pipe flow of Newtonian and power law fluids into a single master curve. It also discus…
On the Blasius correlation for friction factors
Khanh Tuoc Trinh
The Blasius empirical correlation for turbulent pipe friction factors is derived from first principles and extended to non-Newtonian power law fluids. Two alternative formulations…
A Zonal Similarity Analysis Of Friction Factors: Case Study 1: Pipe Flow Of Power Law Fluids
Khanh Tuoc Trinh
A zonal similarity analysis of friction factors in pipe flow of power law fluids is presented. It uses the critical Reynolds number and friction factor at transition as estimates o…
On The Critical Reynolds Number For Transition From Laminar To Turbulent Flow
K. T. Trinh
In this visualisation, the transition from laminar to turbulent flow is characterised by the intermittent ejection of wall fluid into the outer stream. The normalised thickness of…
Logarithmic Correlations For Turbulent Pipe Flow Of Power Law Fluids
K. T. Trinh
This paper uses the estimates of phase-locked parameters at the onset of bursting presented in a companion paper to derive logarithmic correlations for turbulent friction factor lo…
On the Karman constant
K. T. Trinh
Numerous studies in the past 40 years have established that turbulent flow fields are populated by transient coherent structures that represent patches of fluids moving cohesively…
The Instantaneous Wall Viscosity in Pipe Flow of Power Law Fluids: Case Study for a Theory of Turbulence in Time-Independent Non-Newtonian Fluids
Khanh Tuoc Trinh
This paper presents a new theory of turbulence in time-independent non-Newtonian fluids. The wall layer is modelled in terms of unsteady exchange of viscous momentum between the wa…
A Four Component Decomposition of the Instantaneous Velocity in Turbulent Flow
Khanh Tuoc Trinh
A four component decomposition of the local instantaneous velocity is proposed. It brings out more readily the terms in the Navier-Stokes equations associated with different events…
