Special Purpose Computer Program for Large Diameter (10-30ft)
Gas-Gas Heat Exchanger Design

gas heat exchangerSpecialized equipment oftentimes do not lend themselves to standard design tools or even Finite Element Analysis which can be expensive for complex equipment and require individuals with background in FEA. In this case the client's design methodology used a combination of experience, hand calculations, spreadsheets and subcontracted analysis using proprietary software. Their desire was to have all the design done in one comprehensive in-house software package with the capability of investigating multiple design options rapidly. Over an elapsed time of about one-year Becht developed Windows based application with a user friendly interface for the design of large diameter, fixed tubesheet, gas-to-gas heat exchangers. The program, uses the method of finite differences supplemented with built in subroutines, e.g., materials allowable stresses, perforated tubesheets, etc. based on ASME Code Section VIII, Div. 1 rules. The program was validated using more elaborate FEA methods.
