Syllabus

  • Getting Started & Source Models: Liquid Leaks
    • After this module, you will be able to describe the terms that make up the mechanical energy balance. You will be able to apply the mechanical energy balance to derive a simple source model for a liquid leak through a hole and be able to extend the simple source model for liquid leak through a hold to account for a situation where the change in liquid level is significant. You will also be able to incorporate frictional losses in piping systems into liquid source model derivation.
  • Soure Models: Gas Leaks
    • After this module, you will be able to apply the mechanical energy balance to derive a simple source model for a gas leak through a hole. You will also be able to use models of adiabatic and isothermal gas or vapor flows through pipes and understand challenges with deriving models for such flows. You will be able to estimate volatile vapor component concentrations in enclosed spaces and assess the potential for hazardous concentrations and be able to describe source model selection for scenarios involving flashing liquids.
  • Dispersion: Plume Models
    • After this module, you will be able to describe air dispersion and the parameters required to describe it. You will be able to formulate neutrally buoyant plume dispersion models. You'll also be able to perform calculations using plume models and use results to identify potential hazardous situations and propose prevention/mitigation measures if necessary.
  • Dispersion: Puff Models
    • After this module, you will be able to formulate neutrally buoyant puff models and be able to describe isopleths and how they are used in evaluating puff models. You will be able to perform calculations using puff models and use results to identify potential hazardous situations and propose prevention/mitigation measures if necessary.
