Fluids: The molar gas constant also known as gas constant or ideal gas constant, has been updated. This value is internally used by the application for the calculation of the Vapour Density in condensation calculations. The former used value was 8.314472 J·mol-1·K-1 as defined in "CODATA recommended values of the...

Thermal Balance: Fluids: Fixed a problem in the data table that prevented users from removing values. The figures were visually removed from the interface but the underlying data remained in the table.Fluids: Fixed a rounding problem in the data table (temperature column) when values of other columns were edited in...

Thermal Balance: Thermal Conductivity:: In previous versions thermal conductivity of materials (AISI 304, 316, 316L, Ti, etc) used in tubes was considered to be a constant for all of them. This part of the program has been enhanced so that thermal conductivity behaves as a variable function depending on temperature....

Geometry: Automatically use all tubes available: When the number of tubes is left as 0 and a calculation launched, it is assumed that all avaiable tubes are to be used. When the calculations are finished, this field is updated with the value of maximum number of tubes. Monotubes: When then...

New option to use sealing strips in calculations with baffles.Laminar/Turbulent regime calculation for cases with baffles, now takes into account Reynolds=100 as the only limit among the two possible flow-types (there is no transition zone when calculations are done with full baffle support).Changes in Geometry so that values of Minimum...

During baffles calculations, CentralBaffleSpacing_Lbc now takes into account the cummulative thickness of all baffles.Shell hydraulic diameter, when calculated with full baffles (not the support option), now is set to be equal to the external diameter of the tubes.In the fluid velocity calculations, baffles are now taken into account, when they...

It is now possible to calculate multipass heat exchangers with mechanised headers, with any number of passes, even though this figure is not exactly divisible between the number of tubes. Now there might be a single orphan tube left, maximum. A warning is still being shown when the number of...

Fix in calculations using Baffles. In the last version, because of the introduction of the 'divide and conquer' algorithm, some of the Baffles calculations were left out the overall calculation. This issue has been fixed.Other minor bug fixes and improvements.

Annular Space Heat Exchangers restrictions: Only horizontal geometries are allowed. Only sensible heat calculations are allowed. The program will raise an error when trying to calculate any condensing scenario (either in tubes or in shell) or when trying to calculate a vertical geometry for this kind of heat exchanger. Important...

Fix in Pressure Drop calculations: when multipass heat exchangers were calculated, the module pressure drop for tubes-side was not calculated correctly.Other minor bug fixes and improvements.
