The thermal conductivity bounds are very easily determined from the result (4.183), which is such that the denominator of the third term on the right-hand side is the only term to change value when the properties and volume fractions are interchanged. It then follows that the bounds may be written as

(4.193)

whenever κm≤κTf. Whenever κm≥κTf, the bounds defined by (4.193) should be reversed.
