1. A liner panel for use in a gas turbine engine, the liner panel comprising: a forward circumferential rail, an intermediate rail, and an aft circumferential rail that each extend from a cold side of the liner panel; anda multiple of heat transfer augmentors,wherein the multiple of heat transfer augmentors decrease in height with respect to a distance from the intermediate rail to the forward circumferential rail and the aft circumferential rail. 2. The liner panel as recited in claim 1, wherein the multiple of heat transfer augmentors generally form a gothic arch architecture arrangement. 3. The liner panel as recited in claim 2, wherein an apex of a pointed arch of the gothic arch architecture arrangement is generally adjacent to the intermediate rail. 4. The liner panel as recited in claim 3, wherein an extrados of the pointed arch extends toward the forward circumferential rail. 5. The liner panel as recited in claim 3, wherein an extrados of the pointed arch extends toward the aft circumferential rail. 6. The liner panel as recited in claim 2, wherein the gothic arch architecture arrangement includes a multiple of nested pointed arches. 7. The liner panel as recited in claim 6, wherein an apex of each of the multiple of nested pointed arches of the gothic arch architecture arrangement is arranged generally adjacent to the intermediate rail. 8. The liner panel as recited in claim 7, wherein an extrados of the multiple of nested pointed arches extend toward the forward circumferential rail. 9. The liner panel as recited in claim 7, wherein an extrados of the multiple of nested pointed arches extend toward the aft circumferential rail. 10. A wall assembly within a gas turbine engine, the wall assembly comprising: a liner panel;a support shell with a contoured region to define at least one convergent passage between the support shell and the liner panel;a multiple of heat transfer augmentors that extend from the liner panel toward the support shell; anda forward circumferential rail, an intermediate rail, and an aft circumferential rail that each extend from the liner panel toward the support shell,wherein the multiple of heat transfer augmentors decrease in height with respect to a distance from the intermediate rail to the forward circumferential rail and the aft circumferential rail, the decrease in height corresponding with the contoured region. 11. The wall assembly as recited in claim 10, wherein the multiple of heat transfer augmentors extend from the liner panel partially to the support shell. 12. The wall assembly as recited in claim 10, wherein the multiple of heat transfer augmentors extend from the liner panel a distance about half-way to the support shell. 13. The wall assembly as recited in claim 10, wherein the multiple of heat transfer augmentors extend from the liner panel to the support shell. 14. The wall assembly as recited in claim 10, wherein the multiple of heat transfer augmentors generally form a gothic arch architecture arrangement. 15. The wall assembly as recited in claim 14, wherein an apex of a pointed arch of the gothic arch architecture arrangement is generally adjacent to the intermediate rail. 16. The wall assembly as recited in claim 15, wherein an extrados of the pointed arch extends toward the forward circumferential rail. 17. The wall assembly as recited in claim 15, wherein an extrados of the pointed arch extends toward the aft circumferential rail. 18. The wall assembly as recited in claim 10, wherein the liner panel partially defines a combustion chamber, and wherein the multiple of heat transfer augmentors extend from a cold side of the liner panel in a direction that is away from the combustion chamber. 19. A method of cooling a wall assembly for a gas turbine engine, the method comprising: directing cooling air into at least one convergent cavity between a support shell and a liner panel;the liner panel including a multiple of heat transfer augmentors that extend from the liner panel toward the support shell; anda forward circumferential rail, an intermediate rail, and an aft circumferential rail that each extend from the liner panel toward the support shell,wherein the multiple of heat transfer augmentors decrease in height with respect to a distance from the intermediate rail to the forward circumferential rail and the aft circumferential rail. 20. The method as recited in claim 19, further comprising orienting the multiple of heat transfer augmentors to form a gothic arch architecture arrangement with respect to the intermediate rail.
