Discuss advantages and disadvantages of using a large control volume.
What will be an ideal response?
The advantages of a large control volume are
(1) the numerical solution can be carried out quickly
(2) manual calculation for all control volumes are feasible for the purpose of verifying the numerical
calculation
(3) energy will be conserved
Disadvantages are
(1) large temperature gradients cannot be accurately represented with large control volumes
(2) it is difficult to accommodate all but rectangular geometries.
