Week 1- Mixing Tee

INTRODUCTION

To set up steady-state simulations to compare the mixing effectiveness when hot inlet temperature is 36⁰C & the Cold inlet is at 19⁰C.

Study

1. To study the effect of temperature inside the pipe
2. To study the mixing of air inside the pipe
3. Different cases are considered for the study are stated below
4. Case 1A-short mixing tee
5. Case 1A- long Mixing tee
6. Case 2A- short mixing tee
7. Case 2A- long Mixing tee

Parameters are discussed below

Pre-processing and solver setting

solver prosser is used 2 nos and double precission.
