Heat exchangers are crucial components in various industrial processes, including power generation, chemical processing, and HVAC systems. The design of heat exchangers is a complex task that requires careful consideration of several factors, including thermal performance, pressure drop, and cost. HTRI (Heat Transfer Research, Inc.) is a leading organization that provides design guidelines and tools for heat exchanger design. In this report, we will focus on the HTRI heat exchanger design methodology, specifically the "top" or "shell-and-tube" heat exchanger design.
HTRI is the "Gold Standard" for the process industry. It is not the easiest software to learn, nor the most visually modern, but it is the most scientifically rigorous. If you are designing shell-and-tube exchangers for critical applications (oil & gas, petrochemical, power generation), HTRI is mandatory. htri heat exchanger design top
A superior design is only as good as its data. Top designers prioritize the data. Using HTRI’s internal property generator is convenient, but for complex mixtures or non-ideal fluids, importing property grid files from simulators like Aspen HYSYS or Honeywell UniSim ensures the enthalpy curves and phase changes are captured accurately. Misrepresenting the latent heat or viscosity in the boundary layer is the most common cause of undersized exchangers. 2.
