DESCRIPTION

The Fluid Science range is an innovative suite of products designed to enable students to gain an understanding of the fundamentals of Fluid Mechanics and Thermo Fluids by the process of learning via hands-on experimentation.

The high precision elements are supplied as modular tray-based systems which operate in conjunction with the Fluid Science service unit, multifunctional work panel and instrumentation enabling the student to conduct their own individual or group experiments.

The experiments are supplied with a highly visual user-friendly operational guide, allowing the students to understand the theory of the subject by the application of practical experimentation.

The FS-3.2 Fluid Science Tubular Heat Exchanger tray includes experimentation to demonstrate indirect heating or cooling by transfer of heat from one fluid stream to another when separated by a solid wall (fluid to fluid heat transfer) in a tubular heat exchanger.

The tray introduces students to concepts such as heat transfer coefficients, thermal resistances, controlling resistance and heat transfer driving forces. The heat exchanger can be used in a co-current or counter-current configuration.

EXPERIMENTAL CONTENT

• To demonstrate indirect heating or cooling by transfer of heat from one fluid stream to another when separated by a solid wall (fluid to fluid heat transfer).
• To perform an energy balance across a tubular heat exchanger
• To calculate the overall efficiency at different fluid flowrates
• To demonstrate the differences between co-current flow (flows in same direction) and countercurrent flow (flows in the opposite direction) and the effect on the heat transferred, temperature efficiencies and temperature profiles through a tubular heat exchanger
• To determine the overall heat transfer coefficient for a tubular heat exchanger using the logarithmic mean temperature difference to perform the calculations (for co-current and countercurrent flow)
• To demonstrate the differences between co-current flow (flows in same direction) and countercurrent flow (flows in the opposite direction) and the effect on heat transferred and temperature efficiencies
• To investigate the effect of driving force with co-current and countercurrent flow
