“…Nevertheless, the obtained TF a values indicate that TFWT will generally have a higher contribution to radiation doses than OBT does. There may be a considerable loss of TFWT during storage and culinary processes such as washing, salting and boiling, whereas the loss of OBT before consumption would normally be much less significant (Brudenell et al, 1997;Choi et al, 2002;Chourasia and Goswami, 2007;Diabaté and Strack, 1997). Such a difference between TFWT and OBT may considerably reduce the relative radiological effect of TFWT.…”

“…Chourasia et al applied the RNG k-ε turbulence model with the finite volume solution technique. Average overall errors of 19.5%, 8%, 0.5 o C, and 0.61% were found for air velocity, air flow temperature, product temperature and moisture loss from the potatoes respectively [19,20,21,22]. found that the four different models with their individual prediction accuracy regarding the air velocity were the Standard k-ε model with 24.3 % error, Realizable k-ε model with 23.5 % error, RNG k-ε model with 22.4 % error and SST k-ω models with 18.2% error.…”

Air distribution enable convective heat transfer in cold storage operation. Thermal behaviors of the cold storage system are based on air transport arrangements. Transport characteristics can handle with auxiliary arrangements such as induce draught system. Experimental investigation for the impact of auxiliary draught system (ADS) on air transportation is carried out. Air transport velocity was measured in the cold chamber with a hot wire anemometer. Experimental results show significant enhancement by three times mid-section air flow velocity and overall one- and half-time greater flow velocity observed, while return air velocity measured almost tow time of general condition during the experiment. COP of plant improve by 21% with 25% less time required to achieve desired temperature. 26% saving in power consumption observed during experiments. Auxiliary draught ensures homogeneous environment inside the plant through proper mixing of air and support convective heat transfer. Designing and analysis of airflow patterns with temperature distribution in large entity like cold storage is a difficult task thus Computational Fluid Dynamics (CFD) can address the issue with high degree of precision. It has been observed that SST K-ℇ model has average 26% error with experimental values

“…S. Duret et al 2014, in his experiment, show that return air velocity is higher as compare to air supply velocity in the rear section of cold storage, it causes relatively low heat transfer at the rear section in comparison with cooling coil side [11,12,13]. CFD modeling of cold store units required some specific features as there are large airflow obstacles by means of stockpiling of agricultural goods, air-conditioning systems affect room boundary condition, the evaporator unit can be treated as a source of momentum and low air velocity ± 3m/s with turbulence [14,15,20].…”

Computational Flow Analysis Enables To Demonstrate Large Cold Storage Air Distribution. Thermal Performances Of The Cold Storage Are Based On Airflow Mechanism In A Closed Chamber. Experimental Investigation On Cold Store A Costly Affair Thus, In This Paper The Impact Of Auxiliary Draught System (Ads) On Airflow Distribution Is Carried Out With The Help Of Computational Fluid Dyanamics (Cfd). Experimental Validation Shows A 26% Of Error In Simulation Results. Cfd Results Reflect That Use Of Ads Reduces Cooling Time By 25%. Auxiliary Draught Ensures A Homogeneous Environment Inside The Plant.
