| Abstract: | Gasketed plate heat exchangers (PHEs) are used in refrigeration and heat pump plants and are extensively used in the processing of food and drinks, where the ease of plate cleaning and re-gasketting are important. Existing literatures report on the calculation procedure, performance analysis for different flow configurations, CFD modeling and simulation for different number of plates with various flow patterns as well as passes, analysis charts for flat PHE, etc. However, analysis charts prepared for corrugated PHE are not available in the open literature. In the present study, a 9-plate counter flow corrugated plate heat exchanger is modeled and simulated using computational fluid dynamics (CFD). The performance of the PHE is analyzed using the obtained simulated data in the form of charts such as effectiveness, ε versus number of transfer units, NTU at constant capacity ratio, R; Temperature effectiveness, P versus NTU at constant R and non-dimensional mean temperature difference, θ versus temperature effectiveness, P at constant NTU and R. |
