It has already been mentioned (Table17.1) that the depth of the anterior chamber reduces
with age. This results in an increased velocity (Table17.7) of the AH calculated with the
numerical model. An increased maximum velocity of the AH in the standing position is
also expected, if we use the formula introduced by Canning etal. (2002):

m/(s K) was derived by Canning etal. (2002) for
an ACD of 2.75 mm. If we scale this value to the ACDs of Table17.8 and use as ΔT, the
difference in temperature between the front and back surfaces of ...
