چکیده
Pinch Analysis is an attractive solution for reduction of thermal energy costs in thermo-chemical industries. In this approach, maximum internally recoverable heat determined and a exchange network designed to meet the recovery targets. The performance exchanger over its lifetime however concern Thermal affected by many factors which include physical properties shell tube materials, chemical transfer fluid. study, exchangers targets study simulated. aim paper present predictions performances with different fluids geometries as they undergo fouling degradation. Engineering approaches based on thermodynamic analysis, balance Kern Design equations, well what-if simulation modeling are used work. Shell were internal three process plants, A, B C. These published separate paper. effects degradation tubes-due incremental growth resistance - simulated using Visual Basic (VBA). Overall, it was found that reduces efficiency exponential relationship. An increase 100% leads average 0.37% transfer. Higher values logarithmic mean temperature difference (LMTD) higher ratios external diameter tubes amplify effect exchangers. results work can be applied pinch during design targets, especially predicting how affect these This also useful helping operators determine cleaning intervals avoid loss.

Thermal Performance of Borehole Heat Exchangers
An important issue in the design of systems using borehole heat exchangers is to find costeffective methods to construct the borehole heat exchanger so that heat can be injected or extracted from the ground without excessive temperature differences between the heat carrier fluid and the surrounding ground. This paper presents an overview of experiences and current activities in this field.

متن کاملHigh Performance Woven Mesh Heat Exchangers
Simple-to-fabricate woven mesh structures, consisting of bonded laminates of two-dimensional plain-weave conductive screens, or three-dimensional orthogonal weaves are described. Geometric equations show that these porous matrices can be fabricated to have a wide range of porosity and a highly anisotropic thermal conductivity vector. A mathematical model of the thermal performance of such a mes...
