Thiele modulus defined

Thiele modulus, defined by eq 60 for the ORR potential in phase k, V dimensionless parameter in Figure 11... 

The Ha number (Ham) defined here for the mth sublayer of the membrane layer corresponds to the well-known Thiele modulus defined for catalyst particles, while the Peclet number corresponds to the often used Bodenstein number. 

Here, T is the geometry factor (described in Chapter 6), which depends only on the shape of the catalyst pellet, and 0 is the Thiele modulus defined by... 

Solving the diffusion-reaction equation in the liquid, the enhancement factor can be related to the Hatta number Ha, which is similar to the Thiele modulus defined for heterogeneous gas-solid catalysts. Thus, the Hatta number and its relation to the controlling regime are... 

The payoff for this analysis is shown in Figures 74 3 and 7.14, If we use our first guess for the Thiele modulus, Equation 7.51, we obtain Figure 7.13 in which the various values of

mass balance, Equation 7.54, that the dimensionless reaction rate is... 

When (—r) is given as an integer power law, results analogous to equations (7-8) to (7-11) may be obtained with the Thiele modulus defined as... 

Thiele modulus defined in Equation 22 (dimensionless) Thiele modulus for a first-order reaction (dimensionless) Welsz parameter defined In Equation 38 (dimensionless) Dimensionless time... 

The effectiveness factor depends on the Thiele modulus defined by Equation 18.13.
