ENGR30003: Numerical Programming for Engineers
Assignment 1
August 25, 2019
Marks: This assignment is worth 25% of the overall assessment for this course.
Due Date : Friday, 13 September 2019, 5:00pm, via submit on dimefox. You will lose
penalty marks at the rate of 10% per day Or part day late, an d the assignment will not
be marked if it is more than 5 days late.
Learning Outcomes
This project requires you to demonstrate your understanding of dynamic memory, linked
lists an d basic numerical computation. The key objective of this assignment is to solve a
set of tasks which involve processing of flow around a flat plate.
Flow Around a Flat Plate
In the field of Fluid Mechanics, flow around a flat plate perpendicular to the flow direction
is still an active area of research. With advent of high performance computing and
supercomputers, it has now become possible to look at this simple case with a greater
deal of accuracy. The problem consists of a flat plate that is perpendicular to the main
flow direction as shown in Figure 1 (left). The blue arrows indicate the direction of the
flow while the shaded object is the flat plate. This generates a wake behind the flat plate
and exerts a pressure force on the plate, similar to the force you feel when you hold your
hand out in a moving car. At a given instant the flow behind the flat plate is extremely
complex an d a snapshot of the flow domain is shown in Figure 1 (right).
Working with the Data
For this assignment, you will process the wake data from a flat plate case. The data has
been provided to you in a CSV format file (flow data.csv) with the following form:
rho ,u ,v ,x , y
0.951 ,1.05 ,0 , -15 , -20
0.951 ,1.05 ,0.00155 , -14.6 , -20
0.951 ,1.05 ,0.00273 , -14.2 , -20
0.95 ,1.05 ,0.00366 , -13.8 , -20
0.95 ,1.05 ,0.00434 , -13.4 , -20
0.95 ,1.05 ,0.00467 , -13.1 , -20
0.95 ,1.05 ,0.00462 , -12.7 , -20
Each line corresponds to a point in the flow domain with coordinates (x,y). The density
rho an d velocities at that given point in x an d y are given by u an d v respectively.
