+Class
+    Foam::wallBoilingModels::CHFModels::Tatsumoto
+
+Description
+    A critical heat flux (CHF) sub-cooling correlation model.
+
+Usage
+    Example of the model specification:
+    \verbatim
+    CHFSubCoolModel
+    {
+        // Mandatory entries
+        type            Tatsumoto;
+
+        // Optional entries
+        K               <scalar>;
+    }
+    \endverbatim
+
+    where the entries mean:
+    \table
+      Property  | Description                         | Type | Reqd | Deflt
+      type      | Type name: Tatsumoto                | word | yes  | -
+      K         | Model coefficient                   | scalar | no | 0.23
+    \endtable
