The calculations were implemented using the computer system FlowVision 2.5. As a result of the calculation it was found that the oil with an inlet temperature of 250 C when passing through the fire barrier is cooled to a temperature of 147 C. Calculations indicate the effectiveness of the fire barrier with the proposed dimensions for cooling the oil and need further confirmation. Product Description popup.authors Ballo Yaroslav V.
