+
+Description
+    Variable heat transfer model depending on local values. The area of contact
+    between regions (area) must be provided. The Nu number is calculated as:
+
+        Nu = a*pow(Re, b)*pow(Pr, c)
+
+        and the heat transfer coefficient as:
+
+        htc = Nu*K/ds
+
+        where:
+            K is the heat conduction
+            ds is the strut diameter

-Class
-    turbulentTemperatureCoupledBaffleFvPatchScalarField
-
-Description
-    Harmonic fixed value boundary condition for temperature, to be used
-    for heat-transfer on back-to-back baffles.
-
-    If my temperature is T1, heat conductivity K1 and neighbour is T2,K2
-
-    both sides get fixedValue (K1/dx1*T1 + K2/dx2*T2)/(K1/dx1+K2/dx2)
-
-    Example usage:
-        myInterfacePatchName
-        {
-            type    compressible::turbulentTemperatureCoupledBaffle;
-            neighbourFieldName  T;
-            K                   lookup;
-            KName               K; // or none
-            value               uniform 300;
-        }
-
-    Needs to be on underlying mapped(Wall)FvPatch.
-
-    Note: see temperatureCoupledBase on ways to specify K.
-
-    Note: runs in parallel with arbitrary decomposition. Uses mapped
-    functionality to calculate exchange.
-
-    Note: lags interface data so both sides use same data.
-    - problem: schedule to calculate average would interfere
-    with standard processor swaps.
-    - so: updateCoeffs sets both to same Twall. Only need to do
-    this for last outer iteration but don't have access to this.
