The transport equation relevant to the heavier of two elements forming a gaseous mixture was derived from the following equations.<BR>Heat balance: d<SUP>2</SUP>T/dr<SUP>2</SUP>+(1/r)•(dT/dr)=0<BR>Material balance: d<SUP>2</SUP>υ<SUB>z</SUB>/dr<SUP>2</SUP>+(1/r)•(dυ<SUB>z</SUB>/dr)=α•(T-T<SUB>c</SUB>)<BR>Diffusion equation concerning the heavier element:<BR>∂(rJ<SUB>c</SUB>)∂z+∂(rJ<SUB>DZ</SUB>)/∂z+∂(rJ<SUB>DR</SUB>)+∂(rJ<SUB>TD</SUB>)/∂r=0<BR>Concentration of the heavier element in the radial direction:<BR>C<SUB>1</SUB>(r, z)=C<SUB>1</SUB>(R<SUB>i</SUB>, z)+(r-R<SUB>i</SUB>)K<SUB>1</SUB>.<BR>The transport equation thus derived became that of Jones & Furry when the smaller terms were neglected.<BR>The influence on the separation factor brought by the axial gas velocity υi along the hot wire surface was then analyzed. The results were as follows: <BR>The maximum separation factor displaces toward lower operating pressures when the gas velocity υ<SUB>i</SUB> is increased to a certain degree. It would appear from the present calculation that to obtain maximum separation, lower operating pressures should be combined with higher gas velocity υ<SUB>i</SUB>, while with increasing operating pressure, υt, should have to be gradually reduced, finally to reach zero at a certain pressure.
