### Pre-Requisite Knowledge

Undergraduate modules in fluid mechanics and heat transfer

### Summary of Content

This module introduces the theory which underpins current building simulation techniques used in industry in the fields of dynamic thermal modelling (DTM) and computational fluid dynamics (CFD). The application of current modelling techniques is examined with reference to practical examples.

### Syllabus

Introduction to the idea of dynamic thermal loads: Steady state heat losses & gains vs. CIBSE admittance method. Application of techniques within Dynamic Thermal Modelling (DTM) software Derivation of basic equations for fluid flow: continuity, Navier-Stokes for 3-dimensional viscous flow Turbulence modelling: zero equation models, eddy viscosity models, Reynold's stresses Numerical techniques for solution of partial differential equations: comparison of different techniques, finite volume, finite difference, finite element Application of numerical methods within Computational Fluid Dynamics (CFD) software. Application of DTM and CFD modelling techniques to assess the performance of different design proposals and sensitivity of the design to a variety of internal and external changes to the building.

### Learning Outcomes

:On successful completion of this module students should be able to:Understand steady state and dynamic heat transfer though building fabric with reference to the CIBSE admittance method.Understand the theoretical background to dynamic thermal modelling techniques. Apply standard professional software to build a simple dynamic thermal model and understand it's sensitivity to variations in the building design. Understand the derivation, and key elements, of the Navier-Stokes equations governing fluid flow Understand the concept of turbulence modelling and evaluate the relative merits of different turbulence models for various types of application. Critically appraise numerical schemes and calculation techniques used in computational fluid dynamics simulations. Apply standard professional software to build a CFD model and evaluate the predicted system performance with reference to specified design criteria. Critically appraise building designs based on experience gained in modelling a variety of schemes and evaluating their relative performance.

### Teaching / Learning Strategy

The full range of teaching / learning strategies will be employed to support this module. All teaching material will be made available on the Web and students will interact with each other and the module tutors through GCULearn. Enhancement activities will be organised at the university to support the learning process. Attendance at enhancement activities, while beneficial, is not essential as the learning and teaching assessment strategy is based on delivery of the module via GCULearn. Attendance at university is essential for the computer lab sessions within which the use of the software will be taught.
