Ionic Transport Processes In Electrochemistry and Membrane Science

Modelling of heterogeneous tactics, similar to electrochemical reactions, extraction, or ion-exchange, often calls for fixing the shipping challenge linked to the method. because the techniques on the part boundary are defined by means of scalar amounts and delivery amounts are vectors or tensors, coupling them can ensue merely through conservation of mass, cost, or momentum.

9. In the evaporative section, the evaporation of the coolant liquid takes place resulting in Qv having a positive value. No evaporation and condensation take place in the adiabatic region, and therefore Qv is zero. In the condenser region, the condensation of the coolant liquid takes place resulting Qv being negative. 8 1 X* FIG. 9. position. Heat flux Qv used for the evaporation of liquid along the dimensionless axial B. STEADY-STATE EXPERIMENTAL STUDIES Murakami et al. [102] performed one of the first experimental investigations by studying a flat heat pipe several millimeters thick.

The liquid pressure is a function of radius of curvature and the relationship is given by the Young–Laplace equation in the differential form as @Pl l @R ¼ 2 @x R @x ð23Þ The unsteady state momentum balance in the differential form is given as @Vl @Pl A0 Al dh @ðl Al Vl Þ þ Al þ 2Lh  w þ  l;i Rm À l g sin Al À þ ¼0 @t @x @x 2h4 dx ð24Þ At unsteady state mass balance for liquid in the differential form is given l Al Vl as @ðl Al Þ @ðl Al Vl Þ Qv Rm þ þ ¼0 @t @x l ð25Þ The unsteady state energy balance equation in the differential form can be expressed as l Cpl Al @Tl @Tl þ l Cpl Vl Al À QWb þ Qv Rm ¼ 0 @t @x ð26Þ where Q is the heat flux taken up or released by the coolant liquid from the solid substrate.

LIQUID HEIGHT The coolant liquid height (h) is defined as the maximum thickness of the coolant liquid pool. The expression for the coolant liquid height is given as [33]  cosð þ Þ h ¼ Ro R þ sinð þ Þ À 1 tan à  ð39Þ It was seen from Eq. (39) that the coolant liquid height depended on the contact angle of the coolant liquid–substrate system, the radius of curvature, and the groove geometry. The coolant liquid height should be considered while designing an MHP. C. COOLANT LIQUID TEMPERATURE The liquid temperature was calculated in Suman [33] based on a pre­ defined rate of evaporation, condensation, and liquid thermal resistance.
