Software Rates, Simulates Block Exchangers
BLK consists of a Windows graphical interface and calculation engine based on HTRI's proprietary tube-side heat transfer and pressure-drop correlations. The main input window of the software allows a user to select the type of model desired. The program automatically loads all exchanger geometry.
The program operates in rating, simulation and design modes. In the design mode, it automatically rates a user-specified grid of models, passes and block numbers, and then selects the optimum design. Spreadsheet-style output reports summarize exchanger properties and performance.
The BLK program is currently in final testing at SGL Acotec and, once accepted, will be distributed throughout the company as the standard method of sizing the company's line of graphite block exchangers.
