EMSO is the acronym for Environment for Modeling, Simulation, and Optimization.
EMSO is a graphical environment where the user can model complex processes simply selecting and connecting the equipment models.

This program was developed by two professors at the University of Texas Tech, Dr. Theodore Wiesner of the department of chemical engineering and Dr. William Lan from the department of educational psychology. This virtual laboratory consists of three teams: a cooling tower, a heat exchanger and a packed column for absorption of ammonia. LabVIEW was used as an interface.

Turbine Steam-Consumption Calculator v2.2 will calculate the steam consumption for a turbine of known power and efficiency. The required data are the inlet steam pressure and temperature, and the exhaust pressure. The program will determine the specific and actual steam consumption, and the outlet steam enthalpy, entropy, temperature and quality.

Zip file with Microsoft Excel spreadsheets including calculations such as: rectangular weir flow, pump performances, flat plate deflections, packed scrubber design, orifice sizing, duct calculations, dewpoints of acidic gases, unsteady state heat transfer, catenary equations, compressible flow calculations, cone and circle geometry, control valve sizing and horizontal vessel calibration data. These spreadsheet provided by Mr. Neil Stone of Esco Engineering.

Real-time simulation on a PC bench heat
The installation includes the following equipment:
-- Hot water boiler with circulation pump and regulator temperature ICT configurable,
-- Network with hot water flow to each of the three interchanges,
-- Network with cold water valves three ways to reverse the direction of movement in the interchanges, valve and flow measurement of cold water to each intersection,
-- Multitubulaire exchanger to pass later tubes and a pass later grille, chicanes in the grille, temperature of hot water outlet valve acting on the water cold,
-- Exchanger multitubulaire two passes later tubes, and a pass later grille, chicanes in the grille,
-- Coaxial exchanger,

Model
-- Solving equations material balance and thermal transitional arrangements in the interchanges, cut into 32 volumes of control,
-- Taking into account the inertia due to the heat exchanger itself,
-- Determining factors exchange later tube grille and side depending on properties of fluids and flow conditions. Possibility of establishing the overall coefficient exchange.

Example applications: This model can be used to deepen exchanges thermal profiles of temperature and co against current flows transferred, receipts, traded, coefficient of variation of exchange with the operating conditions ...

Various graphical tools are available for analysis and understanding of the process:
-- Display real-time profiles of temperatures dans les interchanges,
-- Display real-time properties on the movement and the heat exchange between other speeds, residence time, Reynolds, Nusselt, Prandlt, local factors and global exchange, Dq ml, flow, etc…
-- Historical variables processes,
-- Management of thermal losses, with adjustable exchange coefficient (grille - external environment) and ambient temperature,

Simulation in real time on the PC two interchanges to size

All parameters of the installation are subject to change: tubes length, diameter grille, properties of fluids, template options, heat loss, etc. ... The simulator can view the operation of heat exchangers co or against the current, transitional or permanent regime, carry out analyses of flux transferred, receipts, traded, etc. ...
