Specific Dissipation Heat Exchanger (TL)

The mass flow rate of the heat-conducting liquid at each break point in the interpolation table for the relative heat transfer value table. The unit interpolates and extrapolates the values of the break points to obtain the relative heat transfer value of the heat exchanger at any mass flow rate.

The mass flow values can be positive, zero, or negative, but they should increase monotonously from left to right. Their number should be equal to the number of columns in the parameter. Specific dissipation table, SD(mdot1, mdot2). If the table contains lines and For example, the vector of mass flow values should contain elements.

The relative value of heat transfer at each break point is shown in the interpolation table of mass flow rates of a heat-conducting liquid and a regulated coolant. The unit interpolates and extrapolates the values of the break points to obtain efficiency for any pair of mass flow rates of a heat-conducting liquid and a regulated coolant.

The values of the relative heat transfer value should not be negative. They must be aligned from top to bottom in the order of increasing mass flow in the channel for the heat-conducting liquid and from left to right in the order of increasing mass flow in the channel for the controlled coolant. The number of rows must be equal to the parameter size. Thermal Liquid mass flow rate vector, mdot1, and the number of columns corresponds to the size of the parameter Controlled fluid mass flow rate vector, mdot2.

If the heat transfer coefficients are specified in the technical data sheet of your heat exchanger, multiply the indicated heat transfer coefficients by the surface area to calculate the relative amount of heat transfer.

A warning about the relative heat transfer value exceeding the minimum flow heat capacity. The flow heat capacity is the product of mass flow and specific heat, and its minimum value is the smallest of the two flows. This minimum determines the relative amount of heat transfer for a heat exchanger with maximum efficiency and cannot be exceeded. For more information, see the description of the block.

The mass flow rate at each break point in the interpolation table of differential pressure values. The unit interpolates and extrapolates the values of the break points to obtain a pressure drop value for any mass flow rate.

The mass flow values can be positive, zero, or negative and can cover laminar, transient, and turbulent zones. However, they should monotonously increase from left to right. Their number must match the size of the parameter. Pressure drop vector, with which they are combined to form tabular breakpoints.

The absolute inlet temperature is determined by collecting tabular pressure drop data. The reference temperature and inlet pressure determine the density of the fluid assumed in the tabular data. During the simulation, the ratio of the reference fluid density to the actual one is multiplied by the differential pressure value shown in the table to obtain the actual pressure drop.

The mass flow rate below which its value is numerically smoothed to avoid discontinuities that lead to simulation errors at zero flow. Detailed information about the calculations for the heat-conducting fluid side of the heat exchanger can be found in the description of the unit. Specific Dissipation Heat Exchanger Interface (TL).

The volume of liquid in the channel for supplying heat-conducting liquid.

The cross-sectional area of the flow at the inlet and outlet of the channel for supplying heat-conducting liquid. The ports have the same size.

The ability to simulate pressure dynamics in a thermally conductive liquid. If you uncheck this box, the block will remove the pressure derivatives from the equations of conservation of energy and mass of the components. The pressure inside the heat exchanger will be reduced to a weighted average of the two inlet pressures.
