# QUESTION: Simulation of "frying Kadhai"

## Simulation of "frying Kadhai" 3 years 2 months ago #1

 ashwini OFFLINE New Member Posts : 4 Upvotes : 0 Hello, I am trying to CFD analysis of "Kadhai" which is used for frying potato chips, bhaji,sev etc. palm oil is used for frying (temp-180 deg. cent.). oil is being heated with hot flue gases (temp - 1100 deg cent.). arrangement has been made for placing kadhai. Boundary conditions i am givig are as follows. Flue gas in - mass flow flue gas out - pressure out Ht wall - convection ht coeff(200 w/m2K) and temp. I am not getting proper results. can anyone help me with boundary conditions? i am attaching geometry. could not upload image in previous messages. please ignore them.

 Praveen Kumar OFFLINE Moderator Posts : 75 Thanks received : 50 Upvotes : 10 Really Interesting Query!! What is the Objective of the analysis. Expected output from CFD? Is it to find the outlet temperature of Flue gas? The wall HTC values is for the Kadhai and other walls are treated as adiabatic?

 ashwini OFFLINE New Member Posts : 4 Upvotes : 0 expected outputs are to calculate - 1) flue gas outlet temp. 2) Heat transfer wall temprature. heat transfer wall is curved surface of the geometry on which kadhai will be placed. and yes other walls are treated as adiabatic The administrator has disabled public write access.

 ashwini OFFLINE New Member Posts : 4 Upvotes : 0 whether i should make on radiation model as well? if yes which model should be used? For more clarification the image attached is showing only vessel carrying flue gas and kadhai is to be placed on the curved surface(heat transfer wall) shown. Thanks.

In this optimization of air curtain hood is determined having oil fumes vapor using ANSYS CFX. Regards Wali The administrator has disabled public write access. Please login with LearnCAx account.
