Aspen HTFS V7_0-User Guide

Performance of proprietary surfaces can be used and stored in a databank. Exchangers can be modelled with up to 15 process streams in co- or counter-current flow and any complexity of exchanger inlet and outlet geometry.

Allowance is made for hrfs, fittings and changes of section, single or two-phase flow, and single or multiple chokes. Fulll allowance can thus be made for non-linear temperature profiles, and for variation gude heat transfer coefficients and pressure gradients.

Simulation can be on a stream by stream or layer by layer basis. Non-Newtonian fluids are also handled. Calculations are performed on a more detailed basis, with each pass in the exchanger being modeled separately, with 25 calculation points per pass.

Having one stream single pass and the other multipass is also permitted. All guids brand and product names are trademarks or registered trademarks of their respective companies.

When you run your HTFS program on a standalone machine, it will identify the dongle you are using, and then copy the appropriate License file from this directory to the root directory of your HTFS program, where it will then be available for run-time checking.


Air coolers and other crossflow exchangers FIHR: Press the Cancel button if you wish to interrrupt the installation at any point – you will then be asked if you want to leave the setup completely, or resume the process. You can also identify the location of other software you may wish to use with the program, or of other files set up previously by other HTFS programs. Up to nine convection section tube banks containing plain tubes or extended surfaces fins or studs.


Radiative heat transfer in the tube banks. HTFS programs can import process and properties data from all the main process simulators. PSF file link to process simulators. You will be shown the list of files selected. If you did not install the License file s during installation, you will need to do so before you can run the program. The serial number of your program security key. The firebox or convection gkide can be modelled alone.

Tube-side Enhancements – Specified on a pass basis; twisted tapes; enhancement factors; j and f input. The Simulation option in TASC is of uuser form permitting either inlet conditions, or outlet conditions or flowrate to be calculated for either stream given the other two parameters. A standard dongle or ytfs key can be used for either standalone or network licenses. On a standalone installation you will also need a dongle, corresponding to one of your License files, plugged into your machine.


The programs can also be used for plate-fin heat exchangers in stainless steel or titanium. If this is the first HTFS or other Hyprotech program with a or later release date that you have installed, you will be shown the default C: This lets you set your preferred set of units. If you want to change the location of a program, uninstall it first and then re-install it. Forced draught; induced draught; no fans.

Single units xspen multiple blocks in series or parallel with vertical or aspe orientations, can be modelled. You will need to reboot before you can run the program you have just installed, and will be offered the choice of doing so immediately after uxer installation.

DESIGN calculations use a mean coefficient and temperature difference approach, within an iteration to select the number of passes and channels per pass, to meet the constraints on heat load, pressure drop, flow velocity and port pressure loss.
