Molten salt

for direct storage tanks, it will be two tanks of cold and hot molten salt fluid
for in direct storage tanks, it will be heat exchanger of therminol oil in between to maintain the required temperature of cold tank.in this case heat exchanger derate will have a value.
so i need to know if sam introduced hot and cold tanks in one tank to minimize cost and land area. it called a thermocline tank
so i need equations to simulate this kind of tanks and which plants have this type.
Thanks

Dear Saeed Aziz,

SAM's physical trough models can only model a two-tank thermal energy storage system.

Best regards,
Paul.
