  • heat transfer correlation in high Prandtl high schmidt Number Fluid in votator type scraped surface heat exchanger
    Journal of Chemical Engineering of Japan, 1997
    Co-Authors: Hisashi Miyashita, Masamichi Yoshida, Takeshi Yamane, Tatsuo Nishimura
    Abstract:

    An experimental investigation to obtain heat transfer correlation in a Votator type scraped surface heat exchanger with two-blades was performed by an electro-chemical method. Measurements were carried by mass transfer under diffusion control in a ferricyanide/ferrocyanide redox electrochemical reaction. The heat transfer correlation was obtained from an analogy of heat and mass transfer. Local heat transfer coefficients on the wall of the outer column of the exchanger was measured by varying the rotational Reynolds Number, flow rate of Fluid, Prandtl Number and equivalent diameter in order to obtain the unity thermal design equation. The time averaged local Nusselt Number in a high Prandtl Number Fluid was found to be correlated by the following equation: Nu = 1.53Re r 2.51 Pr 0.33 (D o /D e ) 0.44 (1320

  • thermophoresis particle deposition on unsteady two dimensional forced convective heat and mass transfer flow along a wedge with variable viscosity and variable Prandtl Number
    International Communications in Heat and Mass Transfer, 2012
    Co-Authors: Atm M Rahman, M S Alam, M K Chowdhury
    Abstract:

    Abstract In this paper, the effects of thermophoresis particle deposition on an unsteady two dimensional forced convective heat and mass transfer flow past a wedge taking into account the variation of Fluid viscosity and Fluid Prandtl Number with temperature are studied. The local similarity equations are derived and solved numerically using Nachtsheim–Swigert shooting iteration technique along with the sixth order Runge–Kutta integration scheme. Comparisons with previously published work are performed, and the results are found to be in excellent agreement. Results for the non-dimensional velocity, temperature, concentration, Prandtl Number and thermophoretic velocity are displayed graphically whereas thermophoretic deposition velocity is shown in the tabulated form for various values of the pertinent parameters. The obtained numerical results show that in modeling the thermal boundary-layer flow with a temperature-dependent viscosity, consideration of the Prandtl Number as a constant within the boundary layer produces unrealistic results, and therefore, it must be treated as a variable rather than a constant within the boundary layer. The results also show that the thermophoretic particle deposition velocity decreases as the thermophoretic coefficient increases.
