State-Of-The-Art Applied Heat Transfer Seminars

Industrial Heat Exchangers

Date: June 4, 5, and 6, 2008 (8:00 AM - 5:00 PM)
Place: Long Beach, CA.

This course is designed for engineers, supervisors, operators, designers, engineering consultants, project engineers and managers, those who involved in design, engineering, maintenance, operation, and safety of the heat transfer & process equipment.

The three-day short course will cover the elements of thermal and mechanical design of the heat exchangers. All types and industrial / process applications will be discussed. Modern types, such as: Twisted Tube, Advanced Welded Plate, and RODbaffle heat exchangers will be discussed. Corrosion, Fouling, Maldistribution of fluid flow, tube vibration and material selection issues, also numerical examples will be presented. Applicable current industry, TEMA & ASME codes and standards are covered. Also, a PC program such as TDST +(Thermal Design of Shell and Tube Exchangers) will be used for design and rating purposes for Tube-and-Shell heat exchangers. Beside HTRI++ and other software for thermal design and rating of Shell-and-Tube heat exchangers, TDST+ has become, also, one of the most advanced, efficient, accurate and practical software. The input sheet format is self explanatory and user-friendly, therefore, the results of the optimization of the exchanger size will be obtained fast. A comprehensive guide to purchasing a heat exchanger will be presented, which includes information on type selection, purchase specification, evaluating bid proposals, inspection and testing.

Fee: $995.-

Day 1: Introduction, type and classifications of heat exchangers and their applications, modes of heat transfer, tubular & plate heat exchangers, thermal and mechanical design issues.

Day 2: Degradation of performance, introduction to codes and standards, preparation of specifications, Evaluating bid proposals, selecting the right exchanger, inspection, testing, numerical examples, introduction to computer analysis of exchangers.

Day 3: Introduction to TDST+ software, design and rating of Tube-and-Shell exchangers per software for various industrial & process applications, discussion of the results

+:TDST developed by Simulation Heat Transfer, Missouri City, Texas
++: HTRI developed by Heat Transfer Research Inc., College Station, Texas
