CFD Simulation In A Tee Pipe



What is CFD?
Computational Fluid Dynamics (CFD) is a simulations tool that solves fluid flow, heat transfer, and other related phenomenon (mass transfer, combustion and reaction, and multiphase flows) using mathematical equations.

CFD is used as a "Virtual Experiment" which allows the assessment of full three dimensional processes and equipment prior to full CAPEX investment. CFD can be used for:
   •  Process understanding
   •  Equipment Retrofitting and Debottlenecking
   •  Design Optimization
   •  Conceptual Design
   •  Design Validation
   •  Flow Simulation
   •  In a Tee Pipe

Possible Analyses include:
   •  Turbomachinery intake and exhaust system design
   •  Sloshing analysis due to wave loadings
   •  Liquid-liquid or gas-liquid separation process
   •  Subsea pipeline flow regime prediction
   •  Pipeline sand impact assessment and erosion
   •  Thermal plume studies on offshore platforms


What is Corrosion Study?
Corrosion is the deterioration of a metal or its properties. It will attack every component at every stage in the life of every oil and gas field. from casing strings to production platforms, from drilling through to abandonment, corrosion is an adversary worthy of all the high technology and research we can throw at it.

Corrosion is one of the leading causes of failures in onshore transmission pipelines (both gas and hazardous liquids). It also is a threat to gas distribution mains and services, as well as oil and gas gathering systems.

Why Do Corrosion Study?
Corrosion studies provides input on safety issues during the design, operation and regulation of hazardous activities.

In addition, Corrosion studies provides a rational basis for monitoring risks and providing specific decision-making guidance:
   •  Description of the types of corrosion found on pipelines and the methods of management for each
   •  Field data (including assumptions made), e.g. composition of reservoir fluid, pressure, temperature or soil resistivity (for onshore pipelines). Any predicted variations in these factors with field life should be included, as should the level of any uncertainties in the predictions.
   •  The predicted field life and any expected changes in service should be included together with their impact on corrosion related design decisions.
   •  The philosophies of materials selection, corrosion monitoring and mitigation.
   •  The basis for the materials selection.
   •  The proposed corrosion monitoring and mitigation programs.
   •  Factors to consider in deciding which types of corrosion may be a threat to a specific pipeline


What is Noise Study?
Noise Study or also known as Noise Mapping is a map of an area which is coloured according to the noise levels in the area. Sometimes, the noise levels may be shown by contour lines which show the boundaries between different noise levels in an area. The noise levels over an area will be varying all the time.

Why Do Noise Study?
A benefit of having a noise model is that it can be used to assess the effects of high noise level on equipment on peoples. Thus the effect of a proposed new installed equipment can be assessed and suitable noise mitigation can be designed to minimise its impact. This is particularly important in noise action planning, where a cost-benefit analysis of various options can be tested before a decision is made.
